HELP HELP ! Which of the following factors does NOT affect surface currents?


A. Coriolis effect

B. density

C. continental deflection

D. wind

Answers

B density

Surface currents are controlled by three factors: global winds, the Coriolis effect, and continental deflections

The surface currents are affected by the continental deflections, winds and the coriolis effect. Density is not a parameter affecting surface currents. Thus option B is correct.

What are surface currents?

Global wind systems, which are powered by solar energy, propel surface currents. Through these currents, heat is transferred from the tropics to the poles; the Gulf Stream, for example, transports warm water from the eastern US coast up to Northern Europe.

When objects travel far distances around the Earth, they are deflected in a manner known as the Coriolis effect. Currents appear to bend to the right in the Northern Hemisphere and to the left in the Southern Hemisphere due to the rotation of our planet.

Both ocean currents that transferring water current and surface currents are affected by global winds and coriolis affects. But they are not influenced by the density factor.
