Question

PLEASE PLEASE HELP

Which of the following factors interact to create currents that are less than 50 m deep?

A. temperature, gravity, and the Coriolis effect

B. wind, friction, and the Coriolis effect

C. wind, temperature, and salinity

D. density, temperature, and salinity

Answer 1

The answer is density, temperature, and salinity. These are the factors that makes a current that is 50 meter less deep. The other choices will create a higher amplitude of the current.

Answer 2

Factors like "wind, temperature and salinity" interact to create currents that are less than 50 m deep.

Step-by-step explanation:

• Surface ocean currents are mainly governed by the wind system prevalent in that region.

• As the surface ocean water interacts with the wind, it also does interact with the insolation received.

• Water turns warmer or cooler depending on the intensity of insolation. Warmer waters bear the capacity to hold more salt. This makes warmer water a "good carrier of salinity" than cold water.

• More the salinity more is the density of water. Dense water naturally sinks down giving rise to a convection current.

• Thus the wind, temperature and salinity interact with each other to create shallow currents.
