What is the main force that drives deep ocean currents? differences in water densities Coriolis Effect wind continental deflections

## Step 1<br />Deep ocean currents, also known as thermohaline circulation, are primarily driven by differences in water densities. This is due to the fact that the density of seawater is influenced by both temperature and salinity. <br /><br />## Step 2<br />Colder and saltier water is denser than warmer and fresher water. This difference in density causes the water to sink, creating a current. <br /><br />## Step 3<br />The Coriolis Effect, wind, and continental deflections can influence surface currents, but they do not play a significant role in driving deep ocean currents.
