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  while

Deep ocean currents are caused by the difference in the density of the ocean water and temperature gradient and this process is commonly  known as the thermohaline circulation.

Therefore the phrases associated with both deep ocean currents and surface ocean currents are as listed above.
