The flow of the current is responsible for the deep ocean circulation.
EXPLANATION:
When the oceans are driven with density and temperature, Deep ocean currents occurs.
It is caused due to difference in density and temperature. Ocean has huge currents; these currents are formed by the wind.
Density varies in water body which is caused by the temperature variation. Ocean's conveyor belt known as the Thermohaline circulation, denotes for deep ocean density.
