The gravitational pull of the moon tugs on the surface of the ocean until its surface mounds up and outward in the direction of the moon.When the mound of water has reached its highest point it 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 the water and high tide on the opposite side of the earth. Somewhere in between these two high tides are two flat areas on the surfaces of the ocean, these are low tides.

Allow me to expand your response by saying that the effect of the gravitational pull fo the moon affecting the tides do not is not the only factor in causing them to rise or fall. The changing positions of the moon as against the earth, together with the effect of the earth's rotation and water terrain also affect the waters.
