Detailed explanation-1: -It’s gravity which holds our atmosphere to the surface of earth. Gravitational force is an attraction force between two bodies and it is universal. It means it is a natural phenomenon by which all things with mass or energy including planet galaxies and even small bodies are attracted to each other.

Detailed explanation-2: -The Short Answer: Earth’s gravity is strong enough to hold onto its atmosphere and keep it from drifting into space.

Detailed explanation-3: -The atmosphere is held around the Earth by gravity. Gravity pulls gas molecules in the atmosphere toward the Earth’s surface, causing air pressure.

Detailed explanation-4: -Earth’s gravity comes from all its mass. All its mass makes a combined gravitational pull on all the mass in your body. That’s what gives you weight. And if you were on a planet with less mass than Earth, you would weigh less than you do here.

Detailed explanation-5: -But gravity pulls on the atmosphere and holds it to the Earth. Since gravity does have an effect on the atmosphere, we can see that statement (D), it has no effect on the atmosphere, is incorrect.
