Currents Near Buenos Aires and Cape Town
A world map highlights the cities Buenos Aires, Argentina and Cape Town, South Africa, both in the Southern Hemisphere at approximately the same latitude. Arrows form a counter clockwise circle moving north from the South Pole toward cape town, tracing the coast northward, then circling around and turning south along the coast toward Buenos Aires.
Compare the two ocean currents (A and B) shown on the map. Match the current with the phrase that best describes it.

Answered by GPT-5 mini AI
Current A (near Buenos Aires) — a warm, southward-flowing current (Brazil Current)

Current B (near Cape Town) — a cold, northward-flowing current (Benguela Current)

What the map shows:
- The surface circulation (a counterclockwise South Atlantic gyre) and the direction of coastal currents on the west coast of southern Africa and the east coast of South America.

Does the map provide evidence about surface temperatures?
- Yes — it implies the ocean surface temperatures are different. Current A (Brazil Current) is a warm, poleward western‑boundary current, so waters near Buenos Aires are warmed. Current B (Benguela Current) is a cold, equatorward eastern‑boundary current (with upwelling), so waters near Cape Town are cooler.
- (Note: the map shows current directions/types but not measured temperatures; it strongly suggests, however, that the two locations will have different sea‑surface temperatures despite being at similar latitudes.)
