How does gravity support life on Earth?

• by forcing Earth to continuously spin on its axis, which contributes to day and night

• by causing changes in the distance between Earth and the sun, which contributes to the seasons

• by keeping water and gases in the atmosphere close to Earth’s surface, which contributes to life processes

• by preventing meteors and comets from hitting Earth’s surface, which protects living organisms from space fragments
