1 and 3 Only

Humboldt Current - Atacama Desert:

The Humboldt Current is a cold ocean current that flows along the western coast of South America. It originates from the Antarctic waters and moves northward along the coast.

The Atacama Desert is located along the western coast of South America, primarily in Chile and parts of Peru. It is one of the driest deserts in the world.

Canaries Current - Sahara Desert:

The Canaries Current is a cool ocean current that flows southward along the western coast of North Africa, adjacent to the Canary Islands.

The Sahara Desert is located in North Africa, spanning across several countries including Morocco, Algeria, Tunisia, Libya, Egypt, Mauritania, Mali, Niger, Chad, and Sudan.

These pairs are correctly matched based on the geographical relationship between ocean currents and nearby desert regions.
