• 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.
• Low tides occur on the two sides of the Earth
  that are at a 90 degree angle to the moon.
