a ocean currents
b the suns energy
c continental drift
d fishing channels
the gulf stream most impacts the weather in ______.
a west africa
b south america
c central america
d northern europe
which of these currents impacts the united states directly?
a south atlantic
b north atlantic drift
c northern equatorial

Explanation:

First Question:

Wind currents are driven by atmospheric circulation, which is powered by the Sun's energy (solar radiation creates temperature differences, driving wind). Ocean currents affect wind less, continental drift is slow and not direct, fishing channels are human - made and irrelevant. So the answer is B.

The Gulf Stream is a warm ocean current that flows towards Northern Europe, moderating its climate. West Africa is influenced by other currents, South America and Central America are not majorly influenced by the Gulf Stream. So the answer is D.

The North Atlantic Drift (an extension of the Gulf Stream) and other North Atlantic currents can impact the US (e.g., East Coast). The South Atlantic is far from the US, and the Northern Equatorial is in the tropics, not directly impacting the US. Among the options, the North Atlantic Drift (option B) is the one that can impact the US directly.

Answer:

B. the Sun's energy
