Question

Motion of air molecules
The motion type ​

Answer 1

Answer:

Wind is air in motion. It is produced by the uneven heating of the earth's surface by the sun. Since the earth's surface is made of various land and water formations, it absorbs the sun's radiation unevenly. Two factors are necessary to specify wind: speed and direction.

Answer 2

Answer:

Convection is the term describing the upward and downward movement of air (or liquids). The underlying cause of these movements is differences in density. Density is the amount of matter in a given amount of space.

Explanation:

The air in our atmosphere is composed of molecules of different gases. The most common gases are nitrogen (78%), oxygen (about 21%), and argon (almost 1%). Other molecules are present in the atmosphere as well, but in very small quantities.
