Sulphur dioxide is the main cause of acid rain on earth. Volcanoes, sea spray, and rotting vegetation are some of the things that give off sulphur dioxide. The main thing that causes sulphur dioxide to be given off into the atmosphere is the burning off fossil fuels. As sulphur dioxide combines with hydrogen in the atmosphere it become sulphuric acid and then falls down back to the earth, causing acid rain. Another chemical that can cause acid rain is nitric dioxide. These chemicals come mostly from power stations and exhaust fumes.

The effects of acid rain occur in several different places. Lakes are highly polluted by acid rain. Acid rain can reach these lakes in many different ways; one way is acidic snow or rain falls directly into the lakes.

Also the lakes at lower levels receive acid rain when the rain washes away the soil and it flows right into the lakes. Many fish and other life in lakes are dying because of the acid in the water. People are trying to put a stop to this.

Another effect that acid rain has is on the trees. This is probably the most serious effect that acid rain has on the earth. When acid rain combines with the soil below trees it washes away the nutrients that keep trees alive. Also the soils can the give off aluminum, which the trees roots may absorb. This would easily kill trees and even a whole forest if enough of it were given off. Acid rain is very bad for the environment and if something is not done...
