Chapter 14 Vocabulary

3. the distance between the same point on two side-by-side wave forms usually crests or troughs
4. how fast a wave crest moves
7. a current that is set in motion by winds
9. a tide in which the sun's gravity works with the moon's to form high-than-usual tide
11. ocean surface currents are affected by the rotation of the earth through this effect
13. a current that are harder to detect and are deep in the oceans that are much larger than surface currents
15. occurs where sea level is higher than average as surface currents cause the ocean to pile up
16. the time between one wave crest and the next as they pass a stationary point
17. the distance that wind blows over the water's surface in one direction

1. the movement of dense, cold, salty water from the abyssal regions to the surface
2. when crest peaks sharply and then falls over on the forward side of the wave
3. uses the repeated motion of the matter in water to transfer mechanical energy from one place to another
4. the deepest depth below the ocean's surface that is affected by the wave's passage
5. a tide in which the gravity of the moon affects the oceans more than the sun does
6. a tide in which the sun's gravity works against the moon's to form a lower-than-usual tide
8. a type of spiral that changes the current direction with depth
10. dangerous currents that flow perpendicularly away from the beach
12. the vertical distance between the top or crest of the wave and its bottom, or trough
14. a type of current that results from density differences
