Tides

The moon's gravitational force causes earth's tides

Low tides

• Tides are the rising and falling of ocean levels that are caused by the sun and moon's gravitational pull combined with the earth's rotation.

• low tide occurs when the wave's lowest part reaches that specific location.

High tides

• The tidal bulges created by the moon result in high tide for the area facing the moon as well as for the area opposite the moon.

• The high tide on the side of earth facing the moon is typically stronger than the one on the side facing.The two high tides each area on earth experiences are approximately 12 hours and 25 minutes apart.

Multiple Select

• The two high tides each area on earth experiences are approximately 19 hours and 25 minutes apart.

• non-of the above

• The two high tides each area on earth experiences are approximately 12 hours and 25 minutes apart.
