What are two primary forces behind ocean currents?

Besides gravity, the most important forces that cause and affect ocean currents are horizontal pressure-gradient forces, Coriolis forces, and frictional forces.

Also to know is, what are the 2 types of ocean currents?

There are two type of Ocean Currents:

  • Surface Currents–Surface Circulation.
  • Deep Water Currents–Thermohaline Circulation.
  • Primary Forces–start the water moving.
  • The primary forces are:
  • Secondary Forces–influence where the currents flow.
  • Solar heating cause water to expand.

what is the primary reason for the circulation of deep ocean currents? These deep ocean currents are mostly driven by the differences in the density of the water which is caused by the temperature and salinity of the water. This process due to thermal (temperature) and haline (salinity) is known as thermohaline circulation.

Subsequently, question is, what is the primary driver of ocean currents?

Wind is the primary driving force of surface currents. The Coriolis effect deflects the currents to the right (Northern Hemisphere) or left (Southern Hemisphere) of their path of motion (the prevailing wind direction).

What are the three main factors driving ocean currents?

Oceanic currents are driven by three main factors:

  • The rise and fall of the tides. Tides create a current in the oceans, which are strongest near the shore, and in bays and estuaries along the coast.
  • Wind. Winds drive currents that are at or near the ocean’s surface.
  • Thermohaline circulation.
