Determine whether each phrase mainly describes surface ocean currents or deep ocean currents.

- influenced by rotation of Earth
- caused by differences in water
-found closer to the ocean floor
-caused by differences in water
density
- found near the top of the ocean
-caused by prevailing winds

Respuesta :

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.
