The atmosphere is a blanket of gases surrounding the earth. Atmosphere: What does it contain?  Two gases make up the bulk of the earth's atmosphere by volume: nitrogen(78 per cent) and oxygen(21 per cent). The remaining one per cent is composed of' 'trace' gases, the most prevalent of which is argon. The rest of the trace gases, although present in only minute amounts, are very important to life on earth.Two in particular, carbon dioxide and ozone, have a large impact on atmospheric processes.Another gas, water vapour, also exists in small amounts. It varies in concentration from being almost non-existent over desert regions to about 4 per cent over the oceans. Water vapour is important in the formation of weather. The atmosphere has four layers. Atmosphere: The layers Based on tempe

                                   Water:It is blue gold! Water is a precious resource! Water has two qualities that make it a precious natural resource.First, water is absolutely necessary for life.Human beings,animals and plants cannot survive without water.

If it drops by 10 percent, there is a danger of death. water has two unique qualities: It is essential for life and it cannot normally be replaced by another resource. We have many needs for water! Human beings need water for personal use, agriculture and industries. At home, water is necessary for drinking, cooking food, washing, cleaning, toilet use, and gardening.
