Ocean currents are produced by differences in the temperature of the water at different depths.

This statement is incorrect. Ocean currents are primarily driven by three main factors - wind, temperature, and salinity. Winds blowing over the surface of the ocean create friction and generate currents. Temperature also plays a role in ocean currents as warm water is less dense than cold water and tends to rise while cold water sinks, leading to the formation of ocean currents. Salinity or salt concentration in the water also affects ocean currents as water with higher salinity is denser and sinks while water with lower salinity remains closer to the surface. Other factors such as the shape of the coastline, the rotation of the earth, and ocean floor topography also influence ocean currents.
