Planet venus

Venus Venus has been known since prehistoric times and the planet is named after Venus, the Roman goddess of love. It is the second-closest planet to the Sun and it`s often called Earth's "sister planet," because the two are similar in size, gravity, and bulk composition. Because of these similarities, it was thought that Venus might even have life. Venus is also called the Morning star or the Evening star, because it reaches its brightness shortly before sunrise or shortly after sunset. It is the brightest object in the sky except for the Sun and the Moon. During the last few years the scientists have found that Venus and Earth are very different. It has no oceans and is surrounded by a heavy atmosphere composed mainly of carbon dioxide with virtually no water vapor. There are strong winds at the cloud tops but winds at the surface are very slow, no more than a few kilometers per hour. The surfac...

How to deal with water shortage problems?

How to deal with water shortage problems? Water covers more than 70% of the Earth's surface and it is the most valuable resource in the world. We need water to live on this planet otherwise life on Earth wouldn't be possible. Many countries suffer from water shortages. There is no fresh water for people usage. It's actually a major problem in the world but what can we do to decrease this? Firstly, people need to realise that there are many other people in the world who does not have accessibility to water. We can decrease it by not wasting water on pointless things for example long showers and watering flowers outside the house. By doing this we will economize water and it may be possible for other people to use fresh water as well. Secondly, it is really important to keep the water fresh and clean but many factories let their sewage into the groundwater which can cause a pollution and the lack of fresh water a...

Essay on water pollution, global warming, acid rain, deforestation, intensive farming

Water pollution Attention for water pollution exploded in the 1980s. The oil spill of the Exxon Valdez showed many around the world just how horrible the effects of water pollution could be. However, even the Exxon Valdez spill barely touched the surface of the problem of water pollution. The ship spilt only 5% of the oil spilt that year, and oil is just one of many pollutants that people dump into the water every year. Every year, 14 billions pounds of sewage, sludge, and garbage are dumped into the world's oceans. 19 trillion gallons of waste also enter the water annually. The problem of ocean pollution affects every nation around the world. This is especially true because water is able to transport pollution from one location to another. For many years, chemicals were dumped into bodies of water without concern. While many countries have now banned such behavior, it continues to go on today. As the world has industrialized and i...

Saturn

Tallinna Tööstushariduskeskus Saturn Referaat Tallinn 2014 Sissejuhatus Saturn is one of the most interesting planets in the solar system. It is the sixth planet in the solar system, and is most famous for its stunning array of rings. It is a very easy planet to pick out in the sky because it is one of the brightest lights in the shy. It also has a very faint greenish color that makes it stand out from the rest of the objects in the sky ("Astronomy for Kids"). Saturn is the second largest planet in the solar system, Jupiter being the only planet that is bigger. It also has at least eighteen moons, more than any other planet in the solar system. There have been three voyages to this extraordinary planet, and one is still in process today. The Pioneer II traveled to Saturn in September of 1979, the Voyager missions took place in the 1980's...

Should space exploration be a priority

Space exploration should be a priority Since the beginning of time people have wondered about what's really hidden behind the clouds and what goes on there. Before people had the technology to study space, they tried to make sense of the universe with the help of religion. Luckily thanks to the great interest in the subject, the first manned spaceflight happened on April 12, 1961 by the Soviet Union, with cosmonaut Yuri Gagarin aboard. Travelling in space could become very important and useful for people on earth in case something happens to our planet. Many things could happen since humans are taking advantage of earth's natural resources like oil and building dangerous factories that produce toxic waste. With space travel we could find planets that have the material to replace our resources and maybe get rid of the toxic waste we no longer have room here. Besides that, a war could break out involving ...

Analysis of an article

Analysis of an article: ,,"Pealtnägija": Estonians hope to save the planet with meat substitute" (,,"Pealtnägija": eestlased loodavad asenduslihaga planeeti päästa") Getter Suup 03.05.2017 Impact: 8/10 I think that our eating habits and the future of them is an important topic. Since the number of humans living on planet Earth keeps rising, it is important to raise awarness on how the way we eat will affect (and affects) the planet that we're living on. Since the news were published in one of Estonia's biggest newspapers, Postimees, and also in a video format in ,,Pealtnägija", I believe that it will make hundreds of people to change the way they think and might-be even to consume less meat. Still, this topic probably does not have such a great imp...

Global Warming

Global Warming One of the biggest issues our planet and its inhabitants are facing nowadays is global warming. Global warming, also often referred to as the greenhouse effect, has not always been a problem. However, over the last centuries, since the Industrial Revolution things have changed. Polar regions are melting, species are dying, climate zones are shifting, migration patterns for animals such as polar bears and birds are being disrupted ­ our world as we know it is changing. Some scientists believe that the climate will reach a tipping point, a point at which even a tiny additional increase would throw the system into violent change. We started doing harmful things and only now do we realize what we have done and what we are doing. At this current rate by the middle of next century the Earth's temperature may rise a predicted from 2 to 6 degrees Celsius. This may not seem as much but with the E...

The Little Prince

The narrator, an airplane pilot, crashes in the Sahara desert. The crash badly damages his airplane and leaves the narrator with very little food or water. As he is worrying over his predicament, he is approached by the little prince, a very serious little blond boy who asks the narrator to draw him a sheep. The narrator obliges, and the two become friends. The pilot learns that the little prince comes from a small planet that the little prince calls Asteroid 325 but that people on Earth call Asteroid B-612. The little prince took great care of this planet, preventing any bad seeds from growing and making sure it was never overrun by baobab trees. One day, a mysterious rose sprouted on the planet and the little prince fell in love with it. But when he caught the rose in a lie one day, he decided that he could not trust her anymore. He grew lonely and decided to leave. Despite a last-minute reconciliation with the rose, the prince set ou...

Samsara

Samsara An hour and a half long movie, which at first seems to be my longest ninety minutes ever, hides some real beauty in it. The movie gives us an opportunity to see every side of our planet. It makes me want to go and see every part of it. Samsara is a kind of movie that, at first, makes you want to change the channel. However, it gets much better the longer you watch it. There is just so much to see. It makes us wonder how is it possible that something that breathtaking even exists. On the other hand, it might be a hard movie to watch for some people, because it is slow and just drags on in places. I am more than sure that there are some who would rather watch paint dry. In addition, there is no one talking in the movie. In conclusion, I would like to say that Samsara is undoubtedly an amazing movie when it comes to showing the planet we live on. However, it is not a movie for everyone. A l...

We do not inherit the earth from our ancestors, we borrow it from our children

We do not inherit the earth from our ancestors, we borrow it from our children Our planet has resources which are necessary for people's everyday life. As the population is growing the resources are decreasing. One of the things that affects the life on the earth is overconsumption. We consume more than what the earth can regenerate. This is a big problem because our exhaustible resources are running out. This is a problem that has huge consequences. It means that in the future people may not have enough resources, beacuse right now we are using too much. Secondly, there is a huge amout of waste and pollution. Clean air is our most valuable resource, but it is getting more and more polluted, in the same way as the water. For example, the pollution of water kills hundreds of thousands of birds and water animals. As a result of pollution , there are holes in the ozone layer, which in its turn loses some of its protection. Pollution is als...

Environtment

The ecological footstep of mankind is getting bigger and bigger by the day. Although everybody seems to acknowledge the problem and also care about the wellbeing and preservation of our planet the situation is only getting worse. Firstly, the ever growing need for energy is taking its toll on the environment. Due to the fast growth of the economical and industrial sector in recent years the need for energy has grown dramatically. Global warming which is responsible for the melting of the ice cap which leads to the rise of sea level is mainly caused by the high use of fossil fuels. Secondly, over-consumption caused by population growth on Earth leads to pollution which is becoming highly dangerous to the environment. The decomposition of materials used nowadays is often hundreds of years long. Unfortunately the number of reusable products is getting smaller by the day. Often the reusable product is also less affordable to the consumer wh...

Carbon capture and storage

Humans are changeing the planet with their ordinary life. The principle cause of climate change is the increase in carbon dioxide concentrations in the atmosphere. The main cause of that is the burning of fossile fuels. This is leading to the global warming. People have discovered a way to reduce the amount of CO2 in the atmosphere. It is possible to seperate the CO2 from the other gases by adding liquid which is very good at absorbing CO2. Then it can be pumped to underground. Scientist came up with this idea because methane gas has been down there for thousands of years and it has not come up. So they expect that the CO2 won't be coming up either. To be sure of that, they are coing to make a test and drill two wells to take purified CO2, inject it into the ground and monitor the physical changes that CO2 undergoes. This technology is really new and it is unknown to people. It has not been proven yet, so people are scared and concerned...

What does it mean to be human? In order to understand who is a human we need to understand what separates us from animals. The word ,,human" comes from homo sapiens which is Latin for ,,wise man". The name itself refers to the exact reason we are special ­ our mental capability. What does ability to think give us and how does it affect out world? Human is a social being and cannot live without expressing himself. In order to communicate clearly we have developed a vast system of symbols ­ languages. There are over 6000 different languages in the world and each language comes with a different culture. Because of our ability to remember, humans are able to transmit information from generation to generation. Humans know their history, because we remember what we have created. Our world-view is more than what is seen to the eye. Homo sapiens is a developing species. Our body has changed and so has our min...

Water pollution and society

Water pollution and society This essay is about fresh water and pollution. It's based on an article by David Krantz and Brad Kifferstein. I read it through and now I'm trying to give the conclusion of the article as well as express my own opinion. 70 percent of planet Earth's surface contain water. Water is the beginning of life and vital natural resource. It's vital for every living organism. That's why we have to keep the water bodies clean and stop polluting our fresh water. It's hard to believe, but planet Earth is in great danger. People can't see the whole picture. They are being indifferent to the future. Everyone thinks about themselves and tries to find a better and easier way to get rid of garbage and waste. Money is everything for them. Money talks and nobody cares about giving a dollar to save the nature. Usually a person thinks that what difference can he make. But if everybody think so, it's o...

Veenus

Veenus Veenus on maaga peaaegu ühesuurune planet ning lähim planet meile. Veenus on väga hele, temast on vaid heledamad Päike ja Kuu. Taevast on ta kergesti leitav. Hommikutaevas nähtavat Veenust nimetatakse Koidutäheks, õhtutaevas nähtavat Ehatäheks. Temperatuur planeedi pinnal on 480°C. Veenuse atmosfäär on ligi 100 korda tihedam Maa omast, Maal on selline rõhk ookeanides 1 km sügavuses. Veenuse atmosfäär sisaldab süsinikdioksiidi 96,5%, lämmastikku 3,4% ja argooni 2% ja hapnikku 0,1%. Vähesel määral (kokku 0.1%) on vingugaasi (CO), vääveldioksiidi (SO2) ja veeauru. Vedel vesi muidugi puudub. Veenuse kollakasvalged pilved kihutavad pöörlemisele vastassuunas (idast läände) kiirusega 350 km/h, tehes täistiiru saja tunniga ehk umbes 60 korda kiiremini kui planeet ise. Pilvkate on mitmekihiline. Põhiline pilvekiht on paarkümmend kilomeetrit paks, ta ulatub 60-70 kilomeetri kõrgusele ning sisaldab...

Presentatsioon keskkonnast

Presentation about enviroment Good afternoon everyone. First, let me introduce myself. My name is Valter and I am a student of Tallinn University of Technology. I'd like to talk about environment, its pollution and protecting. I shall only take 3 minutes of your time. Let me begin with the word enviroment and what it means! It means surroundings in which people, animals and plants exist. These are the things that we need, to be alive, but they are also many man-made things and technical progresses that harm the nature. Therefore we can´t live on this planet without basic components which are needed for human existence - air, water and soil. Firstly air, which is mostly a mixture of oxygen and nitrogen. People, animals and plants can ´t live without air. Without oxygen there would be no fire. So we can see, that air is the basic condition for life on the Earth. Did you know that till 18th century people...

Natural disasters

Natural Disasters: Does Mankind Even Stand a Chance? Throughout time, man has fought valiantly against the forces of nature. We have successfully climbed the tallest mountains, sailed the greatest seas, and defeated the mighty dinosaurs. But we are no match for nature's greatest weapon: Natural Disasters. As far as natural disasters go, the deadly trinity of mudslides, whirlpools, and meteors is man's greatest nemesis. Mudslides strike without warning and with deadly force. Every day, across the world, unsuspecting villagers are hammered by the force of 36,000 tons of that soft wet dirt known as mud, as it cascades down mountains, rolls across plains, swoops through valleys, and takes flight over cliffs. Once the mud strikes, it leaves the villages and cities in ruins, as houses and other structures are quickly destroyed. And just as every day these villages are leveled by these disastrous attacks, the world's top scientists are...

The number of species of plants, animals, and microorganisms, the enormous diversity of genes in these species, the different ecosystems on the planet, such as deserts, rainforests and coral reefs are all part of a biologically diverse Earth. Appropriate conservation and sustainable development strategies attempt to recognize this as being integral to any approach.

Okeaania riikide teke

SISSEJUHATUS Okeaania asub Vaikses ookeanis ning koosneb paljudest väikestest ning madalatest osaliselt asustamata saartest, mida ähvardab kliimamuutustest tulenev meretaseme tõus. Okeaania riike võiks lugeda uuteks riikideks, sest nad on iseseisvunud alles 20. sajandi keskpaigas ja paljud neist on tänini oma kunagiste emamaade sõltlased. Kaugemas minevikus valitsesid neid aga pärismaalaste hõimud ja kunagiste hõimupealikke võim säilis tihti ka kolonistide valitsemise ajal (emamaad kogusid pärismaalastelt makse ja tooraineid, kuid hõimupealikel oli siiski ka oma rahva üle kontroll ja võim). Antud referaadis tahan anda ülevaate iseseisvate Okeaania riikide tekkest, nende ajaloost ning riigisüsteemidest. Okeaaniasse kuuluvad iseseisvad riigid valisin Eesti Entsüklopeedia 15. köite järgi vältimaks arusaamatusi (erinevad allikad annavad erineva andmeid riikide Okeaaniasse kuulumise ja iseseisvuse kohta).

Which is more important-sport or science?

This is something that has had me in two minds for a very long time, why does humanity waste so much time and money on sport and the pursuit of sport when realistically it is just a sideshow, a morale booster for the masses? The sheer volume of money spent each year on sports are actually absolutely ridiculous. Sports have become a monster that is beyond our control. This happens as legitimate scientific research struggles to find funding or a struggle along with tiny handouts from patronising governments around the world. Space exploration is probably the prime example in that it is now, at this stage of human development, more important than ever before that we find ways to make space inhabitable. But instead NASA has become a bit of a joke to the public and space exploration the stuff of B- grade horror movies. The question we have to ask ourselves is this, do sports stars really deserve to be paid five times the salary of a scientis...

Reisimise essee

"The world is a book and those who do not travel read only one page." Saint Augustine of Hippo Travelling is very important in my life. By travelling I can learn other cultures and discover many extraordinary places. It does not matter how far I go I will always learn something new on my way. There are so many different countries and thousands of languages on planet Earth. Every nation has its own culture, which differs from others. When I have been to some exotic country I can understand the people better because I have seen their culture. Learning different cultures makes everything easier to understand. People who do not travel are missing most of the book, their mind is not so opened and they are unimaginative. They are stuck in their everyday routine. Everything that happens farther than their homeland is very strange for them. I feel sad about people who do not travel. Often the peo...

Internet has many uses in my life

Internet has many uses in my life - I use it for studying, tracking weather, playing games, watching movies and listening to music. I mostly use internet in my smartphone. It's more convenient to carry around rather than a computer. At home i prefer my computer ­ it makes studying alot easier as I can type words much faster than with a smartphone or a pen. It's also bigger so it's nice to watch movies with as well. I use my computer a lot less than my phone ­ maybe 2 or three hours a day, whereas I use my phone at all times. - , , , . . , . - , , . , . , - , 2 3 , .

Enivornment in Estonia - Problems and solutions

Environment in Estonia Nowadays environmental problems are too big to be managed by individual persons or individual countries. In other words, it is an international problem. But what are the biggest problems in Estonia,why and how people could solve it? Air, water, and land pollution rank among Estonia's most significant environmental challenges. The combination of 300,000 tons of dust from the burning of oil shale by power plants in the northeast part of the country and airborne pollutants from industrial centers in Poland and Germany poses a significant hazard to Estonia's air quality. Estonia's water resources have been affected by agricultural and industrial pollutants, including petroleum products, which have also contaminated the nation's soil. Some rivers and lakes within the country have been found to contain toxic sediments in excess of 10 times the accepted level for safety...

There should be a complete ban on the advertising of dangerous products like cigarettes and alcohol

There should be a complete ban on the advertising of dangerous products like cigarettes and alcohol There are many legal but dangerous products like cigarettes and alcohol that get a lot of advertising. You can see those advertisements almost everywhere, from streets to television. Should they be banned? Are they useful? Most of these ads are meant for people who don't smoke or drink alcohol and since most of the adults already do one or both of them, they are mainly made for children. It's not like the tobacco or alcohol companies would agree with me on that, but this is how I see it. That makes me agree with the ban, to keep children away from bad habits. People who already smoke or drink mostly don't care about the advertisements and are not affected by them. It can clearly be seen that such adverts are only useful for the companies who gain money from new "addicts". Since new smokers increase ...

How can people reduce the amount of waste?

How can people reduce the amount of waste? There are a lot of problems in the world. Big problem is that enormous amount of waste, that people can not put anywhere. There are not just enough space for it. What can be done for it? Actually, almost all the environmental problems are caused from enormous waste amounts. Waste is poisoning environment and substances poison their eaters. These substances may not kill in a short time, they accumulate into one's body and make damages in many years. Secondly, body do not digest eaten trash. Trash is not the thing one's body should digest. Trash on the ground ­ it is the worst problem which needs solving.

Environment

I'd like to present the main issues of our planet and today i'll name 5 of them. These are air pollution, water pollution, endangered animals, deforestation and rubbish. Air pollution Firstly, lets talk about air pollution, which endangeres our life in cities and also the forests near by. Cars and factories blow poisoned gas in the air and it mixes with the oxygen, so the air that we breathe, becomes dangerous to our health. The ozone layer around the Earth, there is a special type of oxygen called ,,ozone". Ozone is important because it stops ultraviolett radiation from the sun. Many aerosol sprays and factories destroy ozone and they have made a very big hole in the ozone layer. This means that too much ultraviolet radiation now enters the Earth. This is very dangerous because it can cause cancer. Poisonous chemicals ...

Bees

BEES Bees are flying insects closely related to wasps and ants. There are nearly 20,000 known species of bee, in nine recognized families, though many are undescribed and the actual number is probably higher. They are found on every continent except Antarctica, in every habitat on the planet that contains insect-pollinated flowering plants. Bees are adapted for feeding on nectar and pollen, the former primarily as an energy source, and the latter primarily for protein and other nutrients. Most pollen is used as food for larvae. Bees have a long proboscis (a complex "tongue") that enables them to obtain the nectar from flowers. They have antennae almost universally made up of 13 segments in males and 12 in females, as is typical for the superfamily. Bees all have two pairs of wings, the hind pair being the smaller of the two; in a very few species, one sex or caste has relatively short wings tha...

Essay-Environmental problems

As time goes on, society will have to face many problems. The biggest issues are with the environment that is around us. It is surprising how our traditional habits can contribute so strongly to environmental problems. They affect the whole world, even our little country Estonia. We, as individuals, are capable of doing anything to save our world. To begin with, everyday life has been disturbed because of COVID-19. Life stopped during this pandemic not only in China where it started, but also across the globe. When we look at the present situation, very many people are confined to their own homes. In Estonia, students can’t go to school normally, they have to stay behind the computer every day and it is very exhausting. Many parents have lost their jobs because of the virus. And still there are people who won’t listen to the government rules and spread the virus further. Secondly, global warming is increasing at an alarming rate wit...

Class essaay. "Music is the universal language"

Class essay. Music is the Universal Language. Music is everywhere around us.. it is in the wind when it blows.. birds, who are loudly screaming now. The noise of cars.. the noise of humans, expecialli their laughing makes me a little happier everytime when I hear it. There're such beautiful voices. Sometimes we just must stand quiet in center on those voices, and catch their message. Music tells us stories wich were never known. Nowadays young people hear music on MP3. They're like in their own reality. Yes it's great to feel that, but a little bit strange, because when somebody wants to ask something at the bus stop, they can't hear anything. Thats sad. I listen to my iPod too, but sometimes it disturbes me, and then I want to hear the naturalmusic after hearing artificial music, which is just imitted that nature by humans.
