Question

The blanket of air above the Earth’s surface ………..

Answer 1

Hint: The approximately sixty three mile(100km) thick gases covering the Earth is merely a thin layer, relative to the Earth’s diameter of seven thousand twenty six miles at the Equator. The Earth’s atmosphere has five layers, each of a different thickness. The atmosphere gets thinner as it gets higher and closer to space.

Complete Answer:
The blanket of air above the Earth's surface is the atmosphere. An atmosphere is a blanket layer of gases that surrounds a planet or moon. The Earth’s atmosphere gives us the air we breathe. It also keeps our planet warm, blocks harmful rays from the sun, and stops space rocks from hitting us.the majority of radiation that comes from space is blocked by the Earht ‘s atmosphere. The Earth’s atmosphere is equipped with a relatively effective shield, which protects it from such radiation. The percentage of gaseous parts varies depending on the altitude, and the air pressure decreases with increasing altitude, enabling the atmosphere to be categorised as distinct vertical layers. The layer closest to the Earth is the troposphere, where practically all weather occurs. The next layer is a stratosphere where the ozone layer is present. The Mesosphere is a third layer which is the coldest layer of the atmosphere. The other last two layers are thermosphere and exosphere.

Note: Structuring the atmosphere based on composition, we also get the homosphere, where all gaseous components are mixed equally, and the heterosphere,where the gas mixture separates because of the diminishing attraction from the Earth.
