When the mound of water has reached the highest point is called high tide. On the side of the earth opposite the moon, the centrifugal force caused by the earth's rotation produces another mound of water and high tide on the opposite side of the earth. Somewhere in between these two high tides are two flat areas on the surface of the ocean, these are called low tides.
The earth's nearby moon is about 2.17 tines as effective as the m ore massive sun in raising tides on the earth, even though the sun exerts a much greater total force on the earth than does the moon.
Tides are raised in the earth's solid crust and atmosphere as well as in the oceans. Every body in the universe has some tidal effect.
Because gravity tugs on nearby things more strongly than on distant things, the oceans closest to the moon feel the greatest attraction to the moon. Being fluid, these nearby oceans move upward in response to the moon's pull, until there is a balance between the upward force from the moon and the downward force from the earth.
