Water that's on the side of the earth facing the moon will
(a) retreat
(b) rise
(c) stay at the same level
(d) fall
The gravitational pull of the moon affects the water on Earth, causing what we know as tides. To determine what will happen to the water on the side of the Earth facing the moon, we first need to understand how tides work.
Tides occur due to the gravitational attraction between the Earth, the moon, and the sun. When the moon is close to a certain side of the Earth, it exerts a gravitational force that causes a bulge of water on that side, creating a high tide. Similarly, on the opposite side of the Earth, there is another high tide due to the moon's gravitational pull.
However, the water level on the side of the Earth facing the moon will not necessarily stay at the same level. As the moon's gravity pulls the water towards it, the water on that side will rise, leading to a high tide. Therefore, the correct answer would be (b) rise.
