The answer is Wind
Oceant currents are driven by the circulation of wind above the surface's waters, interacting with evaporation, sinking of water at high latitudes.
I think that the two regions would be the Temperate Zone and the Polar Zone, as they're the only climate regions to the south of the 20<span>°S latitude. Check a world latitude map and compare it with a climate map if you're still unsure.</span>
Similarities :Both alluvial fans and deltas deposit sediment.
Difference:
A delta forms when a river empties into a larger body of water. An alluvial fan forms on land where a river emerges from a mountainous area and flows out onto a more gently sloping plain. The decrease in slope causes the river to decelerate and deposit sediment, forming an alluvial fan.
