Because the moon's gravity pulls the water towards it. It bulges out in the middle of the ocean, which sucks the water from its outer edges (the shoreline).

What causes low tide on a coastline?
the moon's force on earth causes high tide and low tide.
What are the effects of the movement of the moon?
The effects are the moon phases, eclipses, and the high tide and low tide.
Explain high tides and low tide?
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: http://highered.mcgraw-hill.com/sites/dl/free/0072482621/59233/5_5.htm
What a neap tide low or high?
No, it's not either of those things. A neap tide is when the difference between low tide and high tide is at a minimum. They occur roughly twice a month, when the moon is at first or third quarter. When the moon is new or full, you get the opposite of a neap tide, a "spring tide", when the difference between low tide and high tide as at a maximum.
What determines whether there will be a high or low tide?
The moon determines if there will be high or low tides.
How do low tide and high tide occur?
The moon.
What if the sun didn't help the moon make a high tide and low tide?
If the sun didn't help the moon make a high tide and low then there wouldn't be such of a high tide and probably when there is a low tide the water will be even further than a regular low tide.
What is the difference between the levels at high and low tide?
the diffrencce between high tide and low is a high tide is by the gravitaion pull of the moon and/or the sun and a low tide is in the middle between the moon an sun
What causes low tide on a coastline?

The two tides of the moon what are they called?

What are one high tide and one low tide?
the moon controls it
What are the effects of the earth and moon's movements?
The effects are the moon phases, eclipses, and the high tide and low tide.
Does the moon's gravity cause low tide or high tide?
The Moon's gravity is the primary cause of tides - all tides, both high and low.
