What are Tides?
  • Tides are created because the Earth and the moon and the sun are attracted to each other, just like magnets are attracted to each other.
  • The moon tries to pull at anything on the Earth to bring it closer.
  •  The Earth is able to hold onto everything except the water.
  • Each day, there are two high tides and two low tides.
  • The ocean is constantly moving from high tide to low tide, and then back to high tide.
