3 TIDES

4 Tides are daily movements of ocean water that change the level of the oceans surface. Tides are daily movements of ocean water that change the level of the oceans surface.

5 What causes tides to occur? The gravitational pull the moon has on the earth causes high and low tides.

6 High tides occur on the sides of the Earth that are closest to the moon and farthest away. High tides occur on the sides of the Earth that are closest to the moon and farthest away. Low tides occur on the two sides of the Earth that are at a 90 degree angle to the moon. Low tides occur on the two sides of the Earth that are at a 90 degree angle to the moon.
