What keeps the earth's atmosphere and atmospheric layers in place?

Question

• Gravity of the sun

Answer 1

The Earth's atmosphere and atmospheric layers are kept in place primarily by the Earth's own gravity, not the gravity of the sun. The force of gravity between the Earth and its atmosphere prevents the gases of the atmosphere from escaping into space.

Answer 2

The Earth's atmosphere and atmospheric layers are kept in place primarily by the Earth's own gravity, not the gravity of the sun. Gravity is what holds the gases of the atmosphere close to the Earth's surface, preventing them from escaping into space.
