Tides, the periodic rise and fall in the levels of large bodies of water, are the product of gravitational forces. They result from the interaction of the Earth with both the sun and the moon, though the moon is the most... More »

Ocean waves are an expression of energy moving through water. The most common ocean waves are caused by surface winds pushing water toward land. Seismic activity can also cause waves, such as tsunamis created by undersea... More »

Tides are formed by a combination of gravitational attraction from the moon and the sun, as well as the centrifugal force generated by the rotation of the Earth. The position of both celestial bodies affects the surface ... More »

All tides, including the cycle of spring and neap tides, are caused by the gravitational pull of the sun and moon on Earth's ocean tides. Each month, the angles and alignment of the sun, moon and Earth work to influence ... More »

According to the National Oceanic and Atmospheric Administration, the tides are caused by the gravitational force that pulls on the water and the forces exerted by the moon and the sun. The gravitational pull of the moon... More »

The moon's gravitational force pulls water towards it, creating a high tide on the surface of the ocean closest to the moon. Also, the centrifugal force created by the Earth and moon orbiting around a central point creat... More »

The bottom layer of the ocean is the coldest because cold water has a higher density than warm water. The colder water sinks to the bottom of the ocean. This movement of water creates the ocean currents. More »
