Black Carbon (must süsinik) Annika Pindis 10A Mis on must süsinik ja kuidas see tekib? Must süsinik on atmosfääri aerosooli koostisosa. Tekib põlemisproduktina, (eriti mittetäielikul põlemisel) fossiilkütustest, bioloogilisest kütusest, biomassist. Esineb nii looduslikest protsessidest kui ka inimtegevusest eralduva tahmana. Musta süsiniku toime Maale Must süsinik soojendab atmosfääri, kuna see on kõige suurema valguse neeldumisvõimega atmosfääris. Tahm vähendab maakera albeedot (päikesekiirguse peegeldumisvõime), muutes lume ja jääga kaetud alad tumedamaks. Mõjutab arktiliste alade jääkatte sulamist.

The Cataclysmic Death of Stars Republished from the pages of National Geographic magazine Written by Ron Cowen March 2007 Ever since he was a teenager, Stan Woosley has had a love for chemical elements and a fondness for blowing things up. Growing up in the late 1950s in Texas, "I did everything you could do with potassium nitrate, perchlorate, and permanganate, mixed with a lot of other things," he says. "If you mixed potassium nitrate with sulfur and charcoal, you got gunpowder. If you mixed it with sugar, you got a lot of smoke and a nice pink fire." He tested his explosive concoctions on a Fort Worth golf course: "I screwed the jar down tight and ran like hell." "kaboomWoosley", now an astronomer at the University of California at Santa Cruz, has graduated to bigger explosions--much bigger. Woosley studies some of the most powerful explosions since the birth of the universe: supernovae, the violent deaths of stars. The universe twi...

Tundra Tundra is the world's youngest biome. It was formed 10 000 years ago. Located at latitudes 55° to 70° North. Almost all tundras are located in the Northern Hemisphere, encircling arctic desert and extending south to the coniferous forests of the taiga. The ecotone (ecological boundary region) between the tundra and the forest is known as the tree line or timberline. Tundra comes from the Finnish word tunturi, meaning treeless plain. It is noted for its frost-moulded landscapes, extremely low temperatures, little precipitation, poor nutrients, and short growing seasons. Dead organic material functions as a nutrient pool. The two major nutrients are nitrogen and phosphorus. Nitrogen is created by biological fixation, and phosphorus is created by precipitation. The most distinctive characteristic of tundra soil is its permafrost, a permanently frozen layer of ground. The average winter temperature is -28°C, but the average summe...
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...
Human overpopulation Liis Lukk MJ15 What is overpopulation? • Overpopulation is an undesirable condition where the number of existing human population exceeds the carrying capacity of Earth. • Human overpopulation is among the most pressing environmental issues • Overpopulation can result from an increase in births, a decline in mortality rates, an increase in immigration, or an unsustainable biome and depletion of resources • Human population has been rising continuously since the end of the Black Death, around the year 1350 • The most significant increase has been since the 1950s, mainly due to medical advancements and increases in agricultural productivity • The recent rapid increase in human population over the past three centuries has raised concerns that the planet may not be able to sustain present or future numbers of inhabitants. Loss of Fresh Water • Most of the freshwater resources are ...
Tallinn 2013 Ott Speek Subject: English Geodesy Study group: GI-21b PETROLEUM PRESENTATION Petroleum (L. petroleum, from Greek: Πέτρα (rock) + Latin: oleum (oil) is a naturally occurring flammable liquid consisting of a complex mixture of hydrocarbons of various molecular weights and other liquid organic compounds, that are found in geologic formations beneath the Earth's surface. The name Petroleum covers both naturally occurring unprocessed crude oils and petroleum products that are made up of refined crude oil. A fossil fuel, it is formed when large quantities of dead organisms, usually zooplankton and algae, are buried underneath sedimentary rock and undergo intense heat and pressure. Petroleum is recovered mostly through oil drilling. This comes after the studies of structural geology (at the reservoir scale), sedimentary basin analysis, reservoir characterization (mainly in terms of porosity and perme...

Different types of forests and their forms of usage TARTU 2010 Forest A forest (also called a wood, woodland, wold, weald, holt, frith) is an area with a high density of trees. Forests cover approximately 30% of land and 9.4% of all the planet earth. They are also responsible for regulating our planet's climate and act as large purifiers of airs, by absorbing carbon dioxide, and giving out oxygen. Different types of forests Forests are divided into following main types: o Tropical forest o Subtropical forest o Plantations o Boreal forest o Temperate forest o Seasonal or monsoon forest Tropical and Subtropical Forests Tropical and subtropical forests, also known as rainforests or tropical rainforests, are lavish and ample forests with broad leave tree. They are mostly found at lowlands near the equator - Asia, Africa, South & Central Am...

Drugs are chemicals that change the way a person's body works. You've probably heard that drugs are bad for you, but what does that mean and why are they bad? Medicines Are Legal Drugs If you've ever been sick and had to take medicine, you already know about one kind of drugs. Medicines are legal drugs, meaning doctors are allowed to prescribe them for patients, stores can sell them, and people are allowed to buy them. But it's not legal, or safe, for people to use these medicines any way they want. Cigarettes and Alcohol Cigarettes and alcohol are two other kinds of legal drugs. (In Estonia, adults 18 can buy cigarettes and alcohol.) But smoking and excessive drinking are not healthy for adults and off limits for kids. Nicotine is the drug in tobacco leaves. Whether someone smokes, chews, or sniffs tobacco, he or she is delivering nicotine to the brain. Each cigarette contains about 10 milligrams of nicotine. Nicotine is what keeps peo...
