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 from the crest to crest or from trough to trough | Wave height |
The horizontal distance from crest to crest or from trough trough | Wavelength |
The currents formed by wind blowing over the surface of water | Surface waves |
The motion of the water particles in a wave is circular | True |
Waves generally transport water | False |
Define Breaker | When a wave's base can no longer support the crest, and the wave collapses |
How shallow does water need to be for a breaker to form | Seashore shallow |
What disturbances can causes a tsunami | Underwater earthquake or landslides, a volcanic eruption, or even ice breaking away from a glacier. |
What causes tides | Gravitational force |
Why does the largest tidal range occur during spring tides | Gravitational pull on the ocean is strongest when the two forces act together |
Why does a neap tide have the lowest tidal range | Gravitational pull act against each other |
The average level of the ocean's surface at any given time | Sea level |
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 |
The _____ distance between the crest and the trough of a wave is the wave height | Vertical |
_____ are the periodic rise and fall of the ocean's surface caused by the _______ force between Earth and the Moon and between Earth and the Sun | Tides and Gravitational |
