What is the energy source for the motion of gas in the atmosphere? What prevents atmospheric gases from flying off into space?

1) SOLAR ENERGY is the energy source for the motion of gas in the atmosphere.

2) GRAVITY prevents atmospheric gases from flying off into space.

Explanation:

1) solar energy is radiant light and heat from the Sun that is harnessed using a range of ever-evolving technologies.

SOLAR ENERGY is the energy source for the motion of gas in the atmosphere and it does this by, fueling the kinetic energy of gas molecules in the atmosphere that spreads them apart.

2) Gravity or gravitational forces are forces of attraction.The gravitational force between the Earth and the molecules of gas in the atmosphere is strong enough to hold the atmosphere close to our surface.

THE GRAVITY OF THE EARTH prevents the escape of gases from the atmosphere. Gravity pulls down the gases and does not allow escape.

report!

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."
