Question

Consider the following statement/statements about ocean currents:

A. Cold currents are usually found on the west coast of the continents in the low and middle latitudes (true in both hemispheres) and on the east coast in the higher latitudes in the Northern Hemisphere.

B. Coriolis force influences only wind systems and has no role in influencing ocean currents.

C. Benguela current is a cold current in the west coast of South America.

D. The mixing of warm and cold currents helps replenish the oxygen and favors the growth of planktons, the primary food for fish population.

How many of the following statement/statements is/are correct?

1. Only one statement is correct
2. Only two statements are correct
3. Only three statements are correct
4. None of the statements are correct

Answer 1

Correct Analysis of the Statements:

A. Cold currents are usually found on the west coast of the continents in the low and middle latitudes (true in both hemispheres) and on the east coast in the higher latitudes in the Northern Hemisphere.

• Correct. This is a well-known pattern of cold ocean currents influenced by atmospheric circulation and the Coriolis effect.

B. Coriolis force influences only wind systems and has no role in influencing ocean currents.

• Incorrect. The Coriolis force plays a crucial role in deflecting ocean currents, influencing their direction.

C. Benguela current is a cold current in the west coast of South America.

• Incorrect. The Benguela Current is indeed a cold current, but it is located off the west coast of Africa, not South America.

D. The mixing of warm and cold currents helps replenish the oxygen and favors the growth of planktons, the primary food for fish population.

• Correct. This is true, as the interaction of warm and cold currents creates nutrient-rich zones, supporting marine ecosystems.
