Q: Importance of atmosphere to man
A: The earth is surrounded by all kind of gases. This layer is called the earth's Atmosphere. Without this atmosphere life on earth isn't possible. [ It gives us air, water, heat, and protects us against harmful rays of the sun and against meteorites. This layer around the earth is a colorless, odorless, tasteless 'sea' of gases, water and fine dust. The atmosphere is made up of different layers
with different qualities. It consists of 78 percent nitrogen, 21 percent oxygen, 0,93 percent argon, 0,03 percent carbon dioxide and 0,04 percent of other gases. The Troposphere is the layer where the weather happens. Above this layer is the Stratosphere and in between them is the Ozone layer, that absorbs the sun's harmful ultraviolet rays. Above the Stratosphere is the Mesosphere, the Thermosphere including the Ionosphere - and the Exosphere. The atmosphere measures about 500 miles (700km). plz visit this site ]
