Answer:
An atmosphere is a layer or a set of layers of gases surrounding a planet or other material body, that is held in place by the gravity of that body.
An atmosphere is a layer or a set of layers of gases surrounding a planet or other material body, that is held in place by the gravity of that body. Sometimes there is a temperature inversion, air temperature in the troposphere increases with altitude and warm air sits over cold air. ... The cold ground cools the air that sits above it, making this low layer of air denser than the air above it.

The atmosphere is the blanket of gases which surrounds Earth.
The warm air near the surface rises and cool air higher in the troposphere sinks. So air in the troposphere does a lot of mixing.
This mixing causes the temperature gradient to vary with time and place.The cold ground cools the air that sits above it, making this low layer of air denser than the air above it.
