Does gravity effect high and low tides?

Answer 1

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 2

Yes, gravity plays a major role in causing high and low tides. The gravitational pull of the moon creates two bulges of water on Earth - one facing the moon and one opposite it, causing high tides. When the moon is at a right angle to the sun, gravitational pull from both the sun and the moon align, creating particularly high high tides (spring tides) and low low tides.

Answer 4

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 5

The Earth and the Moon (and the Sun, to a lesser extent) are in a complicated dance driven by gravity and by the fact that the Earth is about 8000 miles in diameter. From one perspective, we see that the Moon orbits the Earth; but in some respects, we would be almost as accurate in saying that the Earth orbits the Moon.

Higher orbits are SLOWER orbits. The farther away an object is, the more slowly to orbits. So the International Space Station, in an orbit 150 miles up, orbits the Earth every 90 minutes or so, while geosynchronous communications satellites are 22,800 miles up - and take 24 hours to circle the Earth.

But if the Earth is orbiting the Moon, then the oceans at the side nearer the Moon are in an orbit that's 4000 miles too low for its orbital velocity- and the oceans on the far side of the Earth from the Moon are in an orbit that's 4000 miles too HIGH. An object - like a water molecule - that is in an orbit that's too low for its velocity will tend to fall toward - or at least, be pulled toward - the primary. An object that's in an orbit too high for its speed will pull away.

This is also why the Moon's gravity is the real factor for tides, even though the Sun (which is 400 times farther away) is far more massive and has far higher gravity. From the Sun, the difference in distance between the center of the Earth and the near or far oceans isn't that significant.

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

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 8

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 9

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 10

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).
