What is a TIDE? Rise and fall in ocean levels Most observable at the coastlines

What is a TIDE? 2 High tides and 2 Low tides occur daily Approx. 6 1/2 hours apart

What causes TIDES? The Moons gravity pulls up on the oceans because they are not attached to the Earth. The Suns gravity also pulls up on the oceans.

Spring Tides Occur during New and Full moons Earth, Moon, and Sun align Gravity from the Sun and Moon PULL on the oceans in the SAME direction Big difference between High and Low tides

Neap Tides Occur during Quarter moons (Half moons) Earth, Moon, and Sun form a right angle Gravity of Moon and Sun PULL in DIFFERENT directions Little difference between High and Low tides

Tidal Range Difference between High Tide and Low Tide in an area High Tide – Low Tide = Tidal Range Changes with positions of the Moon and Sun
