The video explains ocean currents, which are streams of water moving in definite paths across the ocean. It categorizes them based on temperature (warm and cold) and depth (surface and deep water). The causes of ocean currents include salinity, temperature, Earth's rotation, and planetary winds. The video also discusses how land masses and monsoon winds influence ocean currents.
