Solution
The correct option is B 1600
Atmosphere is the layer of air enveloping the earth at the height of around 1600 km and it consists of many gases. The major components of the atmosphere are nitrogen, oxygen and water vapour. The minor components are argon and carbon dioxide, the trace components include inert gases like methane. The atmosphere protects us from meteors and harmful solar radiation and warms the earth's surface by heat retention. Earth's atmosphere has primary five layers, referred to as spheres. From the lowest to the highest layer, they are the troposphere, stratosphere, mesosphere, thermosphere and exosphere. These five distinct layers have been identified using thermal characteristics, chemical composition, movement and density.
