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)
The phrases that describe surface ocean currents are :
- Influenced by rotation of Earth
- caused by prevailing winds
- found near the top of the ocean
The phrases that describe deep Ocean currents are :
- caused by differences in water
- found closer to the ocean floor
- caused by differences in water density
Surface ocean currents are set in motion/caused by the winds ( global winds ) dragging across the surface of the ocean. these winds are powered by the sun and the pattern of surface ocean currents is wholly determined by the direction of the winds Β while
Deep ocean currents are caused by the difference in the density of the ocean water and temperature gradient and this process is commonly Β known as the thermohaline circulation.
Therefore the phrases associated with both deep ocean currents and surface ocean currents are as listed above.
