The Gulf stream that is a part of the North Atlantic gyre is deeper, narrower, and faster-moving than the portion of the gyre near Europe.  The reason for this difference is:

Deep thermohaline (cold and salty) currents are formed by:

Which of the following contributes to the movement of oceanic plates at the spreading ridges?
