Which statement is TRUE concerning the current of the Gulf Stream?

A Variations in the trade winds affect the current.
B It is slower at the time of neap tides than at spring tides.
C When the Moon is at its maximum declination the stream is narrower than when the Moon is on the equator.
D It reaches its daily maximum speed a few hours before the transit of the Moon.
AI Explanation

The correct answer is A) Variations in the trade winds affect the current. The Gulf Stream is a powerful, warm ocean current that flows along the east coast of the United States. The trade winds, which blow from the northeast, play a significant role in driving the Gulf Stream. Variations in the strength and direction of the trade winds can cause changes in the speed and direction of the Gulf Stream current. The other answer choices are incorrect because: B) The speed of the Gulf Stream is not directly affected by tidal cycles. C) The width of the Gulf Stream is not significantly influenced by the Moon's declination. D) The Gulf Stream's daily speed peaks do not correlate with the Moon's transit.
