Across
- 3. A great circle always has the same diameter as the sphere. Perhaps the most important great circle to a cartographer cardinal-direction
- 5. occurs because flying objects or moving fluids such as winds and ocean currents, tend to follow a straight path.
- 6. occurs where sealevel is higher than average as surface currents cause the oceanto pile up
- 8. marks the east-west position of the sun at its highest point in the sky.
- 10. These are called longitude lines on a globe.
- 11. Gravity drives currents that result from density differences
- 14. Another kind of density current, which is similar to an underwatermudslide or lahar
- 16. daily or twice-daily changes in local sea level
- 18. The movement of dense, cold, salty water from the abyssal regions to the surface
- 19. the time between one wave crest and the next as theypass a stationary point
- 21. he distance between the samepoint on two side-by-side wave forms, usually crests or troughs.
Down
- 1. in motion by winds.
- 2. There are currents deep in the oceans that are much larger than surfacecurrents.
- 4. a smooth transition from the continental slope to the
- 7. how fast a wave crest
- 9. The distance that wind blows over the water’s surface in one direction
- 12. used to measure the height of local sea level.
- 13. The crest peaks sharply and then falls over on the forward side of the wave. Sucha wave is breaking,
- 15. These are slow currents that flow far beneath most major surface currents.
- 17. relatively flat ocean floor
- 20. A water wave uses the repeated motion of the matter in water to transfermechanical energy from one place to another.
