| Question | Answer |
|---|---|
| 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 |
| a tide that has the largest tidal range. | spring tide |
| a tide that has the lowest tidal range | neap tide |
