Determine whether each phrase mainly describes surface ocean currents or deep ocean currents.
igomit [66]

Answer: This is What drives ocean currents

- Surface is primarily driven by wind (friction from wind transfers energy and momentum to surface water)

- Deep is slower, driven primarily by density (salinity and temperature) differences

- Thermocline: dramatic temp drop 50 m from surface bc sun can't shine

- Halocline: dramatic gradient in saline, increase as it deepens

- Pycnocline: resulting change in density (50-1000)
