Question

Which of the following statements about the tides is correct?

a) Tides are entirely a consequence of the gravitational pull of the Moon.
b) Tides are entirely a consequence of the combined gravitational pull of the Moon and the Sun.
c) Centrifugal force caused by the spin of the Earth on its axis contributes to the tide-generating force.
d) Tides are generated partly due to gravitational pull of the Moon and (to a lesser extent) the Sun, and partly due to centrifugal "force" caused by motion of the Earth-Moon system around its center of mass.

Answer 1

Tides are generated partly due to gravitational pull of the Moon and (to a lesser extent) the Sun, and partly due to centrifugal "force" caused by motion of the Earth-Moon system around its center of mass.

correct answer is D

Step-by-step explanation:

The correct statement about tides is (d) Tides are generated partly due to gravitational pull of the Moon and (to a lesser extent) the Sun, and partly due to centrifugal "force" caused by motion of the Earth-Moon system around its center of mass.

Tides are primarily caused by the gravitational pull of the Moon, and to a lesser extent, the Sun.

The tidal forces caused by the Moon's gravitational attraction on the Earth's oceans create two tidal bulges on opposite sides of the Earth. In addition to gravitational forces, the motion of the Earth-Moon system around its center of mass also contributes to the generation of tides.

correct answer is D
