The density of asir ner earth's surface is 1.3kgm-3 and the atmospheric pressure is 1.0×105Nm-2. If the atmosphere had uniform density, same as that observed at the surface of the earth what would be the height of the atmosphere to exert the same pressure? or,h=1.0×105Nm-2(1.3kgm-3)(9.8ms-2)=7850m

Answer:
The atmosphere is the most dense near the surface because of gravity. As one goes higher, the air gets thinner and thinner. ... When water evaporates from lakes and oceans, it turns into a gas and becomes part of the atmosphere.
