wreckage to end up?
the east coast of africa
the west coast of south america
the west coast of the united states
the east coast of the united states

Explanation:

Question 4

To determine why the east coast of South America has warmer climates, we analyze ocean currents:

• The east coast of South America is influenced by the Brazil Current (a warm ocean current), which warms the coastal climate.
• The west coast is influenced by the Humboldt Current (a cold ocean current), which cools it.
• Direct sunlight is not the main reason for the temperature difference between the two coasts here.
• The west coast does not have a warm ocean current, and the east coast does not have a cold one. So the correct option is the one stating the east coast is supplied by a warm ocean current.

To find where the shipwreck off the northwest coast of Africa would end up, we consider ocean currents (like the Canary Current and North Atlantic Gyre):

• The northwest coast of Africa is part of the North Atlantic Ocean's current system. The Canary Current and subsequent currents in the North Atlantic Gyre would carry debris toward the west coast of South America (via the North Equatorial Current and then the South Equatorial Current, eventually reaching the west coast of South America).
• The east coast of Africa is not in the path from the northwest coast of Africa.
• The west coast of the US and east coast of the US are not reached by currents from this area in a direct or likely manner for this wreckage.

Answer:

C. The east coast is supplied by a warm ocean current
