Dodoland in Cyberspace Acid Rain Solution to Pollution Poster by a student from Garneau School, Edmonton, Alberta. The blanket of air around the earth called the atmosphere is full of water. Most of the water moisture is in the form of an invisible gas called water vapour. If it is cooled it forms small droplets called clouds, rain, mist or fog. When the water vapour in the air mixes with gases from factories, or car exhausts, the water vapour dissolves and become acidic.
Sulphur dioxide is created by power plants and metal smelters.
Nitrogen oxide comes from the exhaust of cars. These gases when mixed in the air cause acid rain which can harm trees, and interfers with how plants grow. Fish that are exposed to acid rain cannot get oxygen properly in their gills. The may not lay eggs. Drive less, walk, cycle or share rides.
