Answer:- 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)
