What is the moon’s effecton the Earth?
A
The moon influences the seasons by bombarding the Earth with lunar radiation.
B
The moon reacts with the sun to block harmful radiation from reaching the Earth.
C
The moon has no measurable effect on the Earth at all.
D
The gravitational pull of the moon and sun cause the ocean tides to fluctuate.
Explanation: 

Detailed explanation-1: -The Moon and Earth exert a gravitational pull on each other. On Earth, the Moon’s gravitational pull causes the oceans to bulge out on both the side closest to the Moon and the side farthest from the Moon. These bulges create high tides. The low points are where low tides occur.

Detailed explanation-2: -Gravity is one major force that creates tides. In 1687, Sir Isaac Newton explained that ocean tides result from the gravitational attraction of the sun and moon on the oceans of the earth (Sumich, J.L., 1996).

Detailed explanation-3: -The moon is a major influence on the Earth’s tides, but the sun also generates considerable tidal forces. Solar tides are about half as large as lunar tides and are expressed as a variation of lunar tidal patterns, not as a separate set of tides.

Detailed explanation-4: -High tides and low tides are caused by the moon. The moon’s gravitational pull generates something called the tidal force. The tidal force causes Earth-and its water-to bulge out on the side closest to the moon and the side farthest from the moon.
