question 2 (1 point)
earth revolves around the sun. what keeps earth in orbit around the sun?
o a spherical shape of earth
b rotation of earth around its axis
o c tilt of earths rotational axis toward the sun
d suns gravitational pull on earth

Explanation:

According to the law of universal gravitation, every object in the universe attracts every other object with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. The Sun has a large mass, and the gravitational pull it exerts on the Earth is what keeps the Earth in orbit around the Sun.

• Option a: The spherical shape of the Earth has no relation to its orbital motion around the Sun.
• Option b: The rotation of the Earth around its axis is responsible for day - night cycles, not for its orbital motion around the Sun.
• Option c: The tilt of the Earth's rotational axis toward the Sun is related to the seasons, not for keeping the Earth in orbit around the Sun.
• Option d: The Sun's gravitational pull on Earth is the force that provides the centripetal force required for the Earth's orbital motion around the Sun.

Answer:

d. Sun's gravitational pull on Earth
