Tides occur because the strength of an object's gravity depends on the distance from that object. Gravity is stronger at smaller distances. The moons gravity pulls Earth toward it, causing Earth to wobble around a point about a thousand miles below the surface as the moon orbits. Since the water on the far side of Earth experience slightly less lunar gravity than the rest of the planet it lags behind a bit, creating a high tide.

∙ 8y agoThe tides on Earth are the result of tidal forces, differences in the strength of gravity due to differences in distance. The closer you are to a given object, the stronger gravity you feel. Earth is pulled toward the moon by its gravity, causing it to wobble as the moon orbits. The water on the far side of Earth is somewhat farther from the moon and so experiences slightly weaker gravity than the planet as a whole. As a result, as Earth moves toward the moon, the water on the far side lags behind a little bit.

Where are high tides located in relation to the Moon?
There are "sub-lunar" and "antipodal" high tides. The sub-lunar tide occurs when a place is, roughly speaking, directly "below" the Moon in the sky. It's when the place is as close as possible to the Moon on any particular day. The antipodal tide is the one that occurs right on the other side of the Earth, as far away from the Moon as possible. That's the basics, but there are a lot of complications with the tides, of course.
What is the effect on the ocean when Earth the sun and the moon form a right angle?
I think I understand what you mean. The gravitational force of the sun and the moon pulls the ocean, and this is what causes the changing tides, as the earth spins. When the moon is on the same side of the earth as the sun, or on the direct opposite side from the sun, it's gravitational force compliments the suns force and the tide comes in further and goes out further. This is called a Spring tide. In answer to your question, when the moon is not on the near or far side of the earth (when they make a right angle) the moon opposes the gravitational force of the sun and the tide does not come in as far or go out as far. This is called a Neap tide. The cycle of Spring and Neap tides therefore follows the cycle of the moon (new to full).
Why is there high tides on the side of Earth farthest from the moon?
The moon pulls on the water AND the earth leaving the water on the far side behind.
What do you call the largest tides?
the different tides are high tide, low tide, neaptide, and spring tide. high tide is when the moon is pulling the water into the land on on side of the earth, but on the closest, it is low tide, because it is also pulling it away from land. neap tide is when every thing is eutral, and the same, balanced. the spring tide it when its unnaturally high, or just unnaturally low...... just higher, or lower than high or low tides.
How does the spin of the Earth create tides?
The spin of the Earth causes a bulging effect on the side facing the moon due to gravitational forces. This creates high tides on that side. Simultaneously, another high tide occurs on the opposite side of the Earth due to centrifugal force. As Earth rotates, locations experience two high tides and two low tides each day due to this gravitational interaction.
Why does the tide come in out?
There is a high tide on the side of the Earth that is opposite to the Moon. This is because of the differences in the strength of the Moon's gravity felt at different places on Earth. The water on that far side is subject to a smaller gravitational pull than the center of the Earth and is so is "left behind", forming a tidal bulge. See the "related link" below.
Why is there a high tide on the side of the earth furthest from the sun?
It's obvious why there's a high tide on the side nearest the moon: the water is pulled by the moon's gravity. However, that pull is reduced the further you get from the moon, so on the far side, the water experiences a much reduced pull. That causes it to bulge outwards.
Why is there a high tide on the far side on earth?
Tides occur because the strength of an object's gravity depends on the distance from that object. Gravity is stronger at smaller distances. The moons gravity pulls Earth toward it, causing Earth to wobble around a point about a thousand miles below the surface as the moon orbits. Since the water on the far side of Earth experience slightly less lunar gravity than the rest of the planet it lags behind a bit, creating a high tide.
What is the differences of high tide and low tide?
Low tide is when the waves of the ocean dont reach as far inland, and high tide is obviously when the tide reaches farther inland. This depends on the moon as well.

Why is there high tides on the side of Earth farthest from the moon?
The moon pulls on the water AND the earth leaving the water on the far side behind.
Why do tides occur if earth has more gravity than moon?
While the moon's gravity is weaker than Earth's, especially at Earth's distance from it, it still attracts Earth and everything on it, though not nearly as much as Earth's own gravity does. Lunar tides are not simply a result of the moon's, but rather because the strength of an object's gravity decreases with distance. This means that the side of Earth facing the moon is more strongly attracted to it than Earth's center is, which in turn is more strongly attracted than the far side is. On the side of Earth facing the moon, the moon's gravity partially counteracts Earth's gravity, causing it to lessen slightly, allowing water levels to rise to form high tide. As Earth is pulled toward the moon, water on the far side of Earth, which is less attracted to the moon, lags behind slightly, forming a second high tide. This is why most areas experience two high tides and two low tides per day.

What happens to ocean tide when gravitational pull is at its strongest?
When gravitation pull is at its strongest, we have spring tides. The spring tide reaches far up the beach at high tide, and also goes far down the beach at low tide.

When gravitation pull is at its strongest, we have spring tides. The spring tide reaches far up the beach at high tide, and also goes far down the beach at low tide.
What causes the earth is have tides?
The cause of Earth's tides is gravitational pull from the Moon and the Sun. The Moon's influence on the tide is far, far, stronger than the Sun's, however. The gravity pulls up on the water on the part of the Earth closest to the Moon, as well as causing a bulge on the exact opposite part of the bulge. As the Earth rotates, the location of high tide moves around the world. In every 24 hour cycle, or every full rotation of Earth, there are two high tides and two low tides.
What happens during a spring tide and a neap tide?
During a spring tide, the high water mark would be high up on the beach on the flood, and very far out on an ebb tide. During a neap tide, the high water mark is not so high or so low as during a spring tide.
