Explain what tides are. include high tide and low tide in your answer. make it long this question is worth 30 points.

Tides are caused by gravitational pull of the moon and the sun. Tides are very long-period waves that move through the oceans in response to the forces. the moon's gravitational force pulls on water in the oceans so that there are bulges in the ocean on both sides of the planet. The moon pulls water toward it, and this causes the bulge toward the moon.
