6 multiple choice 2 points
what is the term for the slow circulation of cold, deep ocean water in the atlantic ocean?
north atlantic drift
antarctic circumpolar current
thermohaline circulation
north equatorial current

Explanation:

• For question 4: Evaporation is the process where water changes from liquid to gas due to heating. Precipitation is water falling from the atmosphere (rain, snow etc.). Sublimation is solid to gas. Condensation is gas to liquid.
• For question 5: A watershed is an area where surface water drains into a single river or lake. It's not a treatment plant, man - made canal or underground reservoir.
• For question 6: Thermohaline circulation is the slow circulation of cold, deep ocean water in the Atlantic. North Atlantic Drift is a surface current. Antarctic Circumpolar Current is around Antarctica. North Equatorial Current is in the Pacific and Atlantic (near equator, surface current).

Answer:

1. Evaporation
2. An area of land where all the surface water drains into a single river or lake
3. Thermohaline circulation
