| Question | Answer |
|---|---|
| the periodic rise and fall of the ocean's surface caused by the gravitational force between Earth and the Moon and between Earth and the 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 ocean's surface at 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 crest to crest or trough to trough | wavelength |
| 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 ocean's surface at any given time | sea level |
| the periodic rise and fall of the ocean's surface caused by the gravitational force between Earth and the Moon and between Earth and the Sun | tides |
| the difference in water level between a high tide 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 |
| the gravitational force between Earth and the Moon, and between Earth and the sun causes ____ | tides |
| when a wave reaches a certain height and the base can't support a crest | breaker |
| underwater _______ or landslides, volcanic eruptions, or ice breaking from a glaciers causes a tsunami | earthquakes |
| the motion of the water particles in a wave is _____ | circular |
| a spring tide occurs when Earth, the Moon, and the Sun form a ____ line | straight |
| a neap tide occurs when Earth, the Moon, and the Sun form a ____ angle | right |
| surface waves are the currents formed by ____ blowing over the surface of water | wind |
| (t or f) waves generally transport water | f |
| the largest tidal range occurs during the spring tide because the _________ pull is strongest when 2 forces act together | gravitational |
| the lowest tidal range occurs during a neap tide because the gravitational forces between Earth and the Sun act _____ each other | against |
| up and down | vertical |
| side to side | horizontal |
