Explain high tides and low tide?

Answer 1

The earth shakes normally but the moon stops it. When the moon inevitably loses the earth high tide is generated. High tide is when the sea comes inland and low tide is when it isn't!

Building on that:

Picture the earth as a sphere with liquid ocean. Now, picture the moon orbiting that sphere. As the moon orbits, the moon's gravity pulls against the earth. The water, being liquid, is pulled toward the moon on the side facing the moon. On the sides of the earth not facing the moon, the water is spread thin due to the bulge created by the moons gravity. Interestingly, the side opposite the moon (back side, so to speak) also bulges out. So, as the moon goes around, you have high tide beneath the moon and also on the opposite side of the earth, and low tide on the sides.

Here's a good animation that shows what I attempted to describe:

Answer 2

The Moon pulls on the Earth.

Water is easier for the Moon to pull on so when there's flood the water goes towards the Moon. On the other side of the Earth, there's flood aswell. (0° - 180°)

Ebb is just the water that goes towards where there is flood, so then there is less water. (90° - 270°)

Answer 3

One high and one low tide a day is a tidal pattern.

The above is wrong.

The answer is "diurnal"

Answer 4

high tide occurs when the moon is full and the tide is caused by the magnetic pull.

low tide when the moon is not full.
