🔍 Key Concepts

• General circulation of currents in the South Atlantic Ocean • Location and flow direction of the Agulhas Current off southern Africa • Difference between equatorial currents and mid‑ocean gyre currents

💭 Think About

• Picture a great‑circle or rhumb‑line route from the southern tip of Africa to Argentina. Does this route stay near the equator, or in mid‑latitudes across the basin? • Which of the listed currents actually crosses the South Atlantic between Africa and South America, and which ones mainly run along a coastline? • Think about whether you’d be sailing with a western‑flowing current from Africa toward South America, or an eastern‑flowing current from South America toward Africa.

✅ Before You Answer

• Check which currents on the list are boundary currents (running along a coast) versus open‑ocean currents crossing the basin • Verify on an ocean current chart which named current flows from Africa toward South America in the southern hemisphere • Eliminate any current that is located too far north (near the equator) or on the wrong side of the Atlantic for a southern Africa–to–Argentina passage
