Which of the following would have the greatest effect on the size of tides on Earth?

A. Slowing the rate of rotation of the Moon.

B. Increasing the rate of revolution of Earth.

C. Decreasing the distance between the Moon and Earth.

D. Increasing the distance between the Moon and the Sun.

Answers

B. Increasing the rate of the revolution of the earth

The greatest effect on the size of tides on Earth would be C. Decreasing the distance between the Moon and Earth.

What are tides?

Tides are the regular rise and fall of the sea level caused by the gravitational pull of the Moon and the Sun on the Earth. When the gravitational pull of the Moon or the Sun is strongest in a particular area, it causes the water to bulge and forms high tides.

Tides are caused by the gravitational pull of the Moon and the Sun on Earth's oceans. The strength of this pull is proportional to the mass of the Moon and the Sun and inversely proportional to the square of the distance between them and Earth. So, decreasing the distance between the Moon and Earth would increase the gravitational pull of the Moon, causing larger tides.

Slowing the rate of rotation of the Moon (A) would likely have a small effect on tides.

Increasing the rate of revolution of Earth (B) would not have a significant effect on tides.

Increasing the distance between the Moon and the Sun (D) would not have a significant effect on tides as the Sun's gravitational pull on the Earth's oceans is much weaker than that of the Moon.
