Across
- 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
Down
- 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
