---|---|
The periodic rise and fall of the oceans surface caused by the gravitational force between earth and the moon and between the earth and sun. | tides |
occurs when earth, the moon, and the sun form a right angle; has the lowest tidal range. | neap tide |
the average level of the oceans surface art any given time | sea level |
a wave that forms when an ocean disturbance suddenly moves a large volume of water. | tsunami |
occurs when earth the moon and the sun form a straight line; has the largest tidal range. | spring tide |
the difference in water level between a high tide and a low tide. | tidal range |
the highest part of a wave. | crest |
the lowest part of a wave. | trough |
the vertical distance between the crest and the trough. | wave height |
the horizontal distance from the crest to crest or from the trough to trough. | wave length |
the currents formed by wind blowing over the surface water. | surface waves |
a wave that forms when an ocean disturbance suddenly moves a large volume of water. | tsumami |
the average level of the oceans surface at any given time. | sea level |
the periodic rise and fall of the oceans surface caused by the gravitational force between the earth, sun, and moon. | tides |
the difference in water level between high and low tide. | tidal range |
