. It is also accompanied by some oxides of nitrogen. The emission of these gases cause severe environmental pollution. These gases also dissolve in rain water and make it acidic. The rain containing these dissolved compounds is called acid rain. Acid rain slowly corrodes the historical monuments an..

. Not all plants and animals will be able to make the seasonal shift. Some species will be able to cope with the changes, and others will disappear. A plant migrating to a new region could wipe out native species. For eg., as the warm-water plankton moves north, it leads to a drop..
