Does gravity effect high and low tides?

Answer 1

It's not the moon's gravity alone, but the interaction of the earth and moon. One influence is the fact that the earth-moon system orbits around the common center of gravity of earth-moon. This point is called the barycenter, and it is within the body of the earth since earth's mass is considerably larger than the moon's mass. As the earth wobbles around the barycenter, it tends to push the water out from behind the barycenter. At the same time, the gravitational attraction of the moon is stronger on the water that is moon-side than it is on the water on the opposite side of earth. So there is a high tide bulge on two opposite sides of the earth at once, and of course then there are two low tide areas at roughly 90 degree angles to the high tides.

Answer 2

Effect? That's not just an "effect" - the Moon is what causes the tides in the first place! Well, primarily - the Sun also affects the tides, but to a lesser degree.

The basic mechanism is that the Moon attracts the part of the Earth that is closer to the Moon, stronger than the opposite side. The effect on water is greater, since the water is relatively free to move around. The tides do affect land masses, but since they are not completely flexible, the don't move as much as the water (otherwise, we would hardly notice the tides at all).

Answer 3

yes it is because of the gravity of the moon. the water has elastic particles and the gravity of the moon pull it upward . the nearer the moon is the high tide while the farther the moon is low tide . =)

Answer 4

The moon and the earth both use gravitational pulls to change high tides to low tides. The high tidesw usually occur during spring tides,new moons,or full moons. The lower tides occur during first-quater moons,third-quarter moons,and neap tides.

Answer 5

The Moon doesn't simply "affect" the tides, it is the main cause of the tides.

The side of the Earth that is nearer to the Moon feels more attraction than the side that is farther from the Moon. This difference in gravitation will stretch Earth - trying to pull it apart, so to say. Since water moves easier than the solid Earth... well, it moves, thus causing the tides.

The Sun also participates in the creation of the tides, but its effect is less than that of the Moon.

Answer 6

the Earths tides are a result of a combination of the earths gravity and the gravity of the moon and the affect both the earth and the moon. The first thing you need to understand is that both the Earth and the Moon revolve around a single point Known as the Barycenter. The barycenter is about 1707 kilometers below the earths surface. The moon pulls at the water in the Earths oceans causing them to bulge in the direction of the moon when the moon is overhead. This is easy enough to understand. However there are two tides on the earth. there is another high tide happening on the opposite side of the moon and here there is nothing pulling the water up. The explanation is that when the Moon is over one side of the earth its gravity is pulling at all of the material that makes up the earth It is as a result making the Gravity that is affecting the ocean on the opposite side of the Earth weaker. This makes the water relatively lighter and it bulges upwards as a result. The relationship between the moon moon and the movement of the tides around the Earth is also causing the moon to gradually move further and further from the earth.

Answer 7

The gravity of the Earth holds the water of the oceans to the surface of the planet. The gravitational pull of the Moon (and to a lesser but still measurable extent that of the Sun) pulls water from the Earth and the Earth from the Water! that is why there is a tidal water bulge on the same and on the opposite side of the Earth from the Moon.

Answer 8

The Moon does not just affect the tides; it effects them. The tides are due, in great part, to the gravitation of the Moon. The basic idea is that, being fairly near to us, the Moon attracts one part of the Earth - the part that is towards the Moon - stronger than the other side.

Answer 10

The forces of gravity exerted by the sun and the moon upon earth would cause the tides to change from high to low on a daily basis, how ever some tides will be skipped in certain times of day
