Tide
Storyboard Tekst
- High and low tides are caused by the moon. The moons gravitational pull generates something called the tidal force. The tidal force causes earth and its water to bulge out on the side closest to the moon and the side farthest from the moon.
- As the earth rotates, your region of earth passes through both of these bulges each day. When your in one of these bulges , you experience a high tide. When your not in one of these bulges you experience low tides.
- As earth rotates , the moons gravity pulls on different parts of our planet. Even though the moon only has about 1/100th the mass of the earth, since its so close to us, it has enough gravity to move things around. The moons gravity even pulls on the land , bot not enough for anyone to tell.
- Because of the tidal force, the water on the side of the moon always wants to bulge out toward the moon. This bulge is what we call high tide. As your part of the earth rotates into this bulge of water, you might experience a high tide.
- One thing to note however is that this is just an explanation of tidal force. In real life, the earth isnt a global ocean, covered in an even layer of water. There are seven continents , and the land gets in the way. The continents prevent the water from perfectly flowing the moons pull.
