Tides are caused mainly by <u> </u> in how much the moon's gravity pulls on different parts of Earth.
The force of gravity pulls the moon and Earth toward each other.
The moon's gravity causes high tide on the side closest to the moon.
The moon's gravity pulls Earth, leaving water behind causing an additional high tide.
Low tides occur between the two high tides.
