The atmosphere is held to the earth by ______________.

Answer 1

1. Many atoms of gases contained in the planet's atmosphere have masses, and these atoms and the earth are pulled together by gravity.
2. The world draws all objects into itself due to gravity.
3. In fact, gravity keeps the air around our planet in place, and the envelope of air that surrounds the planet is known as the atmosphere.
4. Gravity is defined as a force that pulls a body toward the earth's center, or any other mass-bearing physical object.

Hence, the atmosphere is held to the earth by gravity.
