Transcript Acid Rain1
Acid Rain is snow or Fog that is polluted by acid in the atmosphere. It is made of sulphur dioxide (SO2) and nitrogen oxide (NOX). When they let go of these into the atmosphere they are carried for a very long time by strong winds and return to the earth as acid rain, snow, fog or dust. BAD damage occurs. Acid Rain damages many things. It can damage trees, lakes, forests, fish, crops, vegetation, and buildings. It can also contaminate water. How can we reduce acid rain Acid rain can take centuries to heal but we can heal it faster. By putting lime or limestone in all the lakes we can cancel the acidity out. Norway and Sweeden use this but other countries don’t often try because of the cost. This only works on lakes not forests and soil though. We can prevent acid rain by using other energies such as hydropower, wind energy, geothermal energy and solar energy. Why don’t we use these then? Coal, nuclear power and hydropower are the cheepest so we don’t use most of these because of the cost. • There is at least 100 acid rain drops in every rain fall • If we didn’t use as much gas there wouldn’t be as much acid rain • About 40% of nitrogen oxide comes from transportation- cars, trucks, buses and trains • About 25% is from generating stations and the rest from industrial, commercial and residential processes. • More then 80% of Canadians live in high acid rain possibilities How are we contributing to acid rain We drive our cars for almost no reason at all. Some people gets drives to a place a block away. Some people leave their t.v. on all day and their not even using it. We leave lights on during the day when there’s plenty of light any way. Sometimes you need electricity but sometimes you don’t. What we could do to help Acid Rain stop is, Walk more than drive, Not using as much gas, And taking down some of the Power plants. Whenever you start a fire to keep warm, you wouldn’t think but you are actually polluting then environment very much! By burning wood you are polluting the air! Keep the Earth Safe! Acid rain in forests In forests acid rain is making trees grow more If it misses it still slowly and making them goes into the soil die faster. Branches turn and the trees suck it brown fall off and die when they should still up. be healthy. Sometimes whole forests just die off. Lets say some acid rain missed the trees is this Good Bad Doesn’t matter Acid rain in North America North america gets the most acid rain. In 1982 in Canada and America 51,000 people died to sulfur polution caused by acid rain. Is it worse now? Yes it is No but still very bad In Virginia trout streams are being more and more destroyed. They are being slowly eaten away by acid rain. This is what happened in Germany when Acid Rain hit. A) No!! Q: Is Acid Rain always wet?! Acid Rain can be turned into sulphur dioxide gas and chemical salts. This does the same damage. I can hurt the plants more. B) Sometimes C) Yes!! D)Maybe scientist haven’t figured that out yet. A) Nothing What effect does acid rain have on sea life? B) A lot C) Just a Little Bit D) Kills Everything It has a lot to do with sea life because it pollutes the water and that is what the fishes need to breathe so it kills all of the fish Mr. MacIntyre for helping us use PowerPoint Dylan W.
