• Tides are the rise and fall of the ocean.• Tides cycle as the moon rotates around the earth

and as the position of the sun changes.

• TYPES OF TIDES• High tide = Where the sea level is at it’s highest.• Low tide = Where the sea is at it’s lowest.• The weather can affect the tide, but the location of

the moon has the biggest impact.
