Question

define atmospheric .​

Answer 1

Answer:

An atmosphere is a layer of gas or layers of gases that envelope a planet or other material body, which is held in place by the gravity of that body. A planet retains an atmosphere when the gravitational force is high and the temperature of the atmosphere is low. 

Answer 2

• The air around you has weight, and it presses against everything it touches. That pressure is called atmospheric pressure, or air pressure.

• It is the force exerted on a surface by the air above it as gravity pulls it to Earth.
