Deep ocean currents form when denser ocean water sinks. The flow of deep currents is also affected by the Coriolis effect and by continental deflection. What is the order in which deep ocean currents will form?

a. Water cools and becomes more dense. Dense water sinks towards the ocean floor. Warm surface currents flow toward the polar region. Energy from the warm water is transferred to the cooler atmosphere.

b. Warm surface currents flow toward the polar region. Energy from the warm water is transferred to the cooler atmosphere. Water cools and becomes more dense. Dense water sinks towards the ocean floor.

c. Water cools and becomes more dense. Warm surface currents flow toward the polar region. Dense water sinks towards the ocean floor. Energy from the warm water is transferred to the cooler atmosphere.

d. Energy from the warm water is transferred to the cooler atmosphere. Water cools and becomes more dense. Dense water sinks towards the ocean floor. Warm surface currents flow toward the polar region.
