tides

Tides A tide is: the periodic rise and fall of the water level in the ocean. There are two major tides //high tides and low tides. These changes are common along the coastline.//

//**Low Tide:**// when the water is at its lowest.
 * //High tides://** when the water level is at its highest.

The cause of tides is the moons gravitational pull on us. The sun gravity also causes tides but the sun is very far away. Therefore the moon has more effect on us. This gravitational force is strongest on the side of the earth that is closer to the moon. Because of this near side and far side effects this causes bulges. Most locations in the ocean have two high tides and two low tides daily because of these bulges. We have spring tides and neap tides. Spring tides are when the earth, moon, and sun are aligned and we have high high tides and low low tides. This happens during full and new moons. Neap tides happen when the moon and the sun are at a right angle in relation to the earth. They occur during 1st and 3rd quarter moons.
 * //TIDAL RANGE://**The difference in levels of ocean water at high tide and low tide. It can vary widely because the moon rises about 50 minutes later each day.
