Most observable at the coastlines. What is a TIDE?. 2 High tides and 2 Low tides occur daily. Approx. 6 1/2 hours apart. What causes TIDES?. Moon-Earth Relationship. The . revolution. of the Moon around the Earth makes the Moon look as if it is changing shape in the sky.. This is caused by the different angles from which we see the lighted part of the Moon's surface.  . Description of Waves. A wave is the rhythmic movement that carries energy through space or . matter. Waves are generated by wind flowing over the water . surface.

The moon travels through space in two ways:. Highways in the Sea. What forces are responsible for currents?. Wind. : transfers energy through friction on surface; causes currents and waves. Sea level. : steeper slope=greater pressure gradient=drives a larger, faster current. Moon’s Effect On Tides Warm-Up Activity In 3-5 sentences explain what you think happens to form tides. Gravity Gravity is stronger when objects are closer together. The moon will pull the water on the side of Earth nearest it more strongly than it pulls on Earth itself.
