oceans waves
| Question | Answer |
|---|---|
| the periodic rise and fall of the oceans surface caused by gravitational fore between earth and the moon and between earth and the sun. | tide |
| occurs when earth, the moon, and the sun form a right angle; has lowest tide | neap tide |
| the average level of the oceans surface at any given time | sea level |
| a wave that when an ocean disturbance suddenly moves a large volume off water | tsunami |
| occurs when earth, the moon, and the sun form a strait line; has the largest tidal range. | spring tide |
| the difference in water level between a high tide and a low tide. | tidal range |
| 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 crest to crest or trough to trough | wave lengh |
| the currents formed by wind blowing over the surface of water | surface waves |
| a wave that forms when an ocean disturbance suddenly moves a large volume of water | tsunami |
| the average level of the oceans surface at any given time | sea level |
| the periodic table rise and fall of the oceans surface caused by the gravitational force between the earth and the moon and between the earth and the sun | tides |
| the difference in water level between a high tide and a low tide | tidal range |
| a tide that has the largest tidal range | spring tide |
| a tide that has the lowest tidal range | neap tide |
| highest part of a wave | crest |
| lowest part of a wave | trough |
| the _ distance between the crest and the trough of a wave is the wave height | vertical |
| the horizontal distance from crest to crest or trough to trough i the _ | wave lengh |
| surface waves are the currents formed by _ over the surface of water | wind blowing |
| what is a tsunami | a very large wave |
| what causes tides | gravitational force from earth, moon, and the sun. |
| why does a neap tide have the lowest tide | the sun, earth, and moon make a right angle. |
