How do the causes of surface and deepwater currents differ?

Surface currents are caused by wind; deepwater currents are caused by differences in water density.

Surface currents are caused by the Coriolis effect; deepwater currents are caused by differences in water density.

Surface currents are caused by differences in water salinity; deepwater currents are caused by differences in water temperature.

Surface currents are caused by differences in water density; deepwater currents are caused by wind.

Surface currents are caused by differences in water salinity; deepwater currents are caused by differences in water temperature causes of surface and deepwater currents differ.

Explanation:

The density of seawater fluctuates all-inclusive because of contrasts in temperature and saltiness. Surface water is warmed by the sun, and warm water is less thick than cold water. Surface breeze drove flows produce upwelling flows related to landforms, making deepwater flows.

Flows may likewise be brought about by thickness contrasts in water masses because of temperature (Thermo) and saltiness (haline) varieties through a procedure known as thermohaline dissemination. A blend of high saltiness and low temperature close to the surface makes seawater sufficiently thick to sink into the profound sea and stream along the base of the bowls.

i would say your answer would be the second option.

hope this !

the tariff was created to protect industry in the northern part of the united states. industries in the north were being driven out of business by imported goods that were priced at a low rate. the goal was to protect these industries   by taxing the goods.
