Miina Härma Gymnasium Acid Rain Report Compiler: Teisi Timma 8a Teacher: Esther Linask Tartu 2009 Acid Rain Acid rain is rain consisting of water droplets that are unusually acidic because of atmospheric pollution - most notably the excessive amounts of sulfur and nitrogen released by cars and industrial processes. Acid rain is also called acid deposition because this term includes other forms of acidic precipitation such as snow. Acidic deposition occurs in two ways: wet and dry. Wet deposition is any form of precipitation that removes acids from the atmosphere and deposits them on the Earth's surface. Dry deposition polluting particles and gases stick to the ground via dust and smoke in the absence of precipitation. This form of deposition is dangerous however because
Acid rains Stefani Nimtsuk What is acid rain? Rain or any other form of precipitation that is unusually acidic It can have harmful effects on plants, aquatic animals, and infrastructure through the process of wet deposition Acid rain is caused by emissions of compounds of ammonium, carbon, nitrogen, and sulfur which react with the water molecules in the atmosphere to produce acids History Since the Industrial Revolution, emissions of sulfur dioxide and nitrogen oxides to the atmosphere have increased In 1852, Robert Angus Smith was the first to show the relationship between acid rain and atmospheric pollution in Manchester, England Though acidic rain was discovered in 1852, it was not until the late 1960s that
Acid rain is rain or any other form of precipitation that is unusually acidic. It can have harmful effects on plants, aquatic animals, and infrastructure through the process of wet deposition. Acid rain is caused by emissions of compounds of ammonium, carbon, nitrogen, and sulfur which react with the water molecules in the atmosphere to produce acids. Governments have made efforts since the 1970s to reduce the production of sulfuric oxides into the Earth's atmosphere with positive results Since the Industrial Revolution, emissions of sulfur dioxide and nitrogen oxides to the atmosphere have increased
Environmental effects Very obvious environmental effect of acid rain is the loss of fish in acid sensitive lakes and streams. Loads of fishes are not able to survive in acidic water. There are 2 ways acid rain effects lakes and streams: chronic and episodic. The first one is long-term process and this acidification is result from years of acidic rainfall. Episodic, on the other hand, is rapid change sudden jump in the acidity of water. Acid deposition may influence forest vegetation and soils. It removes soil nutrients such as calcium and magnesium from soils in high elevation forests. Acid rain may also help weaken natural defenses of some trees, making them more vulnerable to some diseases and pests. Acid rain wears away the waxy protective coating of leaves, damaging them and preventing them from being able to photosynthesize properly. Many animals and insects are sensitive to acidification
Environmental problems: acid rain Elza Lutt 10.a What is acid rain? • Acid rain is a rain or any other form of precipitation(sademed) that is unusually acidic, meaning that it has elevated levels of hydrogen ions (low pH). What is it caused by? Wet deposition- niisked sademed Consequences of acid rains • forests, freshwaters(mageveekogud) and soils • Kills insect and aquatic life-forms • Paint peels off from buildings etc. • Corrosion(söövitus) of steel structures • human health What can be done to decrease acid rains • curbing the release of the pollutants(saasteained) References • https://en.wikipedia.org/wiki/Acid_rain • https://www.nationalgeographic.com/environment/
ENVIRONMENTAL PROBLEM The term acid rain refers to what scientists call acid deposition. It is caused by airborne acidic pollutants and has highly destructive results. Scientists first discovered acid rain in 1852, when the English chemist Robert Agnus invented the term. From then until now, acid rain has been an issue of intense debate among scientists and policy makers. Acid rain, one of the most important environmental problems of all, cannot be seen. The invisible gases that cause acid rain usually come from automobiles or coal-burning power plants.
This is how the museum looks like from the outside. Here are our students in front of the Ristna Sea Store sign. The most common components of marine debris in the Baltic Sea are food waste and packages. 31-43% of marine debris are plastic bottles and even 50-63% of marine debris is plastic. Marine debris is harmful for everyone. It causes garbage ingestion and entanglement for marine animals. For marine life it causes accumulation and spread of toxic compounds and garbage deposition. These pictures are illustrative. Ristna Sea Store is organized into different departments and that's why it's called Store. From that exhibition you can find differend findings and their decomposition times in nature. This is how the exhibition looks inside. On this map they have tagged all the countrys where all these findings have came from to the coast of Hiiumaa. -- Departments... All this garbage decomposes for a really long time. For example this plastic bottle

For centuries after the Romans, there were no "wedding dresses", a wealthy bride wore fancier versions of her everyday clothes, the poor and middle classes wore their best dress, often fancied up with ribbon and garlands. In ancient times, a coin was broken by a young man and half given to his intended and half for himself. The broken coin represented his intent to return. Burials Early Anglo-Saxon burials are traditionally based on cremation on a prye, with the deposition of corposes in the ground in a pottery container. Later, the unburned body was depodited in a rectangular grave. Graves were also commonly furnished with goods including jewellery, ornaments, brooches, beads, girdle-hangers and weaponry. Pottery and other vessels are sometimes found, as are toilet-sets, knives and amuletic items. Contribution Anglo-Saxon art contributed some distinctive iconographic forms to the artistic mainstream and also stylistic elements

As the world has industrialized and its population has grown, the problem of water pollution has intensified. The simple fact that millions of people live along coastlines and near rivers means that these bodies of water are likely candidates for heavy and destructive pollution. It is hard to know now what our oceans will look like in the future. Just how damaged they will be by pollution is uncertain. Acid rain The term acid rain refers to what scientists call acid deposition. It is caused by airborne acidic pollutants and has highly destructive results. Scientists first discovered acid rain in 1852, when the English chemist Robert Agnus invented the term. From then until now, acid rain has been an issue of intense debate among scientists and policy makers. Acid rain, one of the most important environmental problems of all, cannot be seen.

Site- specific, localized increase of an antimicrobial secondary metabolite (phytoalexin) was found in the apoplast of S. bicolor in response to the fungal pathogen · Colletotrichum graminicola. The accumulation of phytoalexin starts with the occurrence of spherical cytoplasmic inclusions of about 1 m in diameter that merge to form a large entity of ~ 20 m diameter. · Similarly, during barley-powdery mildew interaction the deposition of H2O2 containing vacuole struc tures were observed. · Ultrastructural analysis showed that these vesicle-like bodies consist of a broad range of cellular structures that includes miniature cell wall appositions, para-mural bodies, and multivesicular bodies. · This condition reflects the specialized transport of different antimicrobial proteins, regulatory polypeptides, cell wall components, and other defense-related cargo.

son of the King or Queen of England. Edward II became Prince of Wales in 1301. He was the first English prince to hold the title Prince of Wales. The Welsh are said to asked the King to give them a prince who spoke Welsh and he answered he would give them a prince that spoke no English at all. As a king, his tendency to ignore his nobility in favour of low-born favourites led to constant political unrest and his eventual deposition. Edward is perhaps best remembered for being the first monarch to establish colleges in the universities of Oxford and Cambridge. *Fergus Mor Mac Earca and Dalriada Fergus Mór mac Eirc was a legendary king of Dál Riata. He was the first king of the Scots in Scotland. He started a large-scale migration to Scotland which resulted in the establishment of a Scottish kingdom called Dalriada. Fergus was allowed to settle in Scotland as a federate of Arthur. Fergus brought the Stone of Scone

conventional silver tabbies. The photo below shows a non-agouti amber. According to Rui Pacheco, although this cat is clearly non-agouti because of the black nose, he has the phenotype of a silver shaded. Rui's theory is that the amber gene invalidates the action on the non-agouti gene; wide-banding will further lighten the base colour giving a very pale cat with black nose and paws. Amber cats are basically black cats with a colour modifier that affects the deposition of pigment on the hair shaft, but not the skin colour. That is why in non-agouti cats the nose remains black and in agouti cats it remains pink. PLATINUM The platinum effect is found in some lines of Silver Persian/Chinchilla Longhair.
