Tides

The gravitational pull of the moon and sun has an effect on Earth objects, but none so visible and spectacular as that on water.

The phenomenon of tides is caused by the gravitational forces drawing water from oceans and seas in different directions causing it to rise and ebb. High and low tides fill and empty coastal areas with more prominent effects taking place at the time  of full and new moons, the equinox and supermoons.

Tidal ranges record the difference between high and low tide levels on the shore. The highest tides are recorded at the Bay of Fundy in Canada.
