Question

8. If the distance between the Earth and the Sun

were increased, which change would occur?

A) The apparent diameter of the Sun would

decrease.

B) The amount of insolation received by the

Earth would increase.

C) The time for one Earth rotation (rotation

period) would double.

D) The time for one Earth revolution (orbital

period) would decrease.

Answer 1

Option C. Time for one Earth rotation would double.

Step-by-step explanation:

If the distance between Earth and Sun is increased up then it will decrease the gravitational pull of the Sun and hence will increase the orbital period of the Earth and will also increase the time taken for one Earth rotation because rotation of Earth is primarily depend on the external torque from the gravity of the Sun, Moon and other celestial bodies.
