Oceanography

4. A mound of sediment that extends away from the continent.
6. A large, continuous mountain range found within an ocean basin; the location on the seafloor where magma upwells and forms new seafloor.
10. The deepest parts of the ocean basins.
12. The edge of a continent that lies under the ocean.
13. The slope between the outer edge of the continental shelf where seafloor slopes toward deep ocean floor.
17. Currents driven by global wind systems that are fueled by energy from the sun.
18. A large stream of moving water that flows through the oceans.

1. A smooth, nearly flat region of the ocean floor comprised of thick layers of sediment.
2. Flowing water deep under the ocean’s surface because of differences in density of ocean water; dense water sinks causing deep water along the ocean bottom to flow.
3. A change in the shape of water caused by energy from wind.
5. The top layer of oceanic crust found on the bottom of the ocean just above the mantle.
7. An underwater mountain with steep sides rising from the seafloor without reaching the water surface.
8. A measure of the amount of dissolved salt in water; average ocean salinity is 3.5%.
9. The regular rising and falling of Earth’s surface waters twice a tidal day as a result of the Moon’s and Sun’s gravitational attraction.
11. The curving of the winds and currents due to the rotation of Earth on its axis; in the Northern Hemisphere, currents curve to the right; in the Southern Hemisphere, currents curve to the left.
14. A powerful, warm, and swift ocean current in the Atlantic Ocean caused by strong winds from the west.
15. Water that contains a high concentration of dissolved salts
16. A huge body of saltwater that covers about 71 percent of Earth’s surface.
