- Cthe motion of Antarctic Bottom Water through the Atlantic Ocean
- Dheavy precipitation directly into the ocean at the equator
- Eformation of Mediterranean Water
16Coriolis Effect forces water into a “hump”, more or less in the middle of each ocean basin, but is countered by the force of gravity which pulls the water down hill. When these two forces are in balance, the flow of water that is established is known as

19To the east of point H in the Mediterranean you'd expect to find ___ productivity due to ___
- Alow / downwelling
- Blow / upwelling
- Chigh / downwelling
- Dhigh / upwelling
