Why is the phase of the Moon is related to the amplitude of the tides?

Answer 1

The gravity of the Moon causes the tides, so the position of the Moon is related to the tides. And the relative positions of the Sun and Moon cause the Moon's phases. So both things are loosely related because they both depend, at least in part, on the position of the Moon.

Answer 2

Tides are caused by the difference in gravitational pull from the moon and from the sun on the near and the far side of the earth.
So when the moon, earth, and sun are in a straight line (full moon and new moon), the gravitational pull of the sun and moon are sort of working together on the same two sides of the earth, and the tides are highest.
When the moon, earth, and sun form a triangle (basically any lunar phase other than new or full), the sun and moon are not working together on the same sides of the earth - they are affecting different portions of the earth and therefore the tides are not as high.

Answer 3

Tides are created because the Earth and the moon are attracted to each other, just like magnets are attracted to each other. The moon tries to pull at anything on the Earth to bring it closer. But, the Earth is able to hold onto everything except the water. Since the water is always moving, the Earth cannot hold onto it, and the moon is able to pull at it. Each day, there are two high tides and two low tides. The ocean is constantly moving from high tide to low tide, and then back to high tide. There is about 12 hours and 25 minutes between the two high tides.

Tides are the periodic rise and falling of large bodies of water. Winds and currents move the surface water causing waves. The gravitational attraction of the moon causes the oceans to bulge out in the direction of the moon. Another bulge occurs on the opposite side, since the Earth is also being pulled toward the moon (and away from the water on the far side). Ocean levels fluctuate daily as the sun, moon and earth interact. As the moon travels around the earth and as they, together, travel around the sun, the combined gravitational forces cause the world's oceans to rise and fall. Since the earth is rotating while this is happening, two tides occur each day.

Answer 4

the moon's gravity... its the pull on the earth that makes the tides go high or low. so when the moon is in full moon or new moon phase it has the strongest/weakest pull on earth-- causing the tides to change--- b/c of its relationsihp to the sun's pull on earth (gravity). when it is a new moon, the gravities make the tides so low becasue the moon has small mass and is closer to the earth so its gravity equals the enormous mass and large distance of the sun from earth essentially cancelling out the gravities causing low amplitude. u can figure out the high tide on the full moon side...

Answer 5

Because the tides are influenced by both the moon and the sun, so that when they line up, or during new or full moon, the tides are at their maximum.

Answer 6

The moon has a gravitational pull.
If the moon is on the side of the earth for a high tide, it will be higher......

Answer 7

sure, the moon has gravitational pull. So the moon does result tides because in accordance to the position the moon is interior the sky, the water is being pulled particularly in that route which leads to tides.

Answer 8

The Moon's gravity has a very slight effect on the water of Earth, causing it to rise slightly (a few feet usually) where the Moon is closest to Earth.
