Question

"Of the following statements about deep-ocean currents, which is/are true? (A) Deep-ocean currents contain water that is high in oxygen. (B) The volume of water involved in the downward movement of deep-ocean currents is equal to the flow of 100 Amazon-sized rivers. (C) Deep-ocean currents often travel faster than ocean surface currents. (D) Deep-ocean currents are initiated by downwelling of cold, dense water near Antarctica and in the North Atlantic Ocean. (E) Deep-ocean currents are important regulators of global climate. (F) Deep-ocean circulation is often referred to as thermohaline flow."

Answer 1

Statements B, D, E, and F out of the given are correct regarding deep-ocean currents. They describe the massive volume of water involved in these currents, the initiation of these currents, their role in regulating global climate, and thermohaline flow.

Step-by-step explanation:

Out of the given statements about deep-ocean currents, the ones that are accurate are B, D, E, and F. (B) It is true that the volume of water involved in the downward movement of deep-ocean currents can be compared to the flow of about 100 Amazon-sized rivers. (D) Deep-ocean currents are indeed initiated by the downwelling of cold, dense water near Antarctica and the North Atlantic Ocean, a process that creates thermohaline circulation. (E) Deep-ocean currents also play a significant role as regulators of global climate as they help distribute heat around the Earth. (F) The term 'thermohaline flow' is used to describe the deep-ocean circulation as it is driven, in part, by differences in temperature ('thermo') and salt content ('haline').
