question 2 (1 point)
suppose we could take the atlantic ocean north of the equator and divide it into two compartments along a north - south line (for example, if sea level were much lower and the mid - atlantic ridge was emergent along its length). what would happen to the north atlantic gyre?
the gyre would grind to a halt because its north and south currents are blocked.
the ridge would have almost no effect, and the currents would just go over or around it.
the mid - atlantic ridge barrier would turn equatorial currents north and northern boundary currents south, resulting in two gyres, one on each side of the ridge.
the ridge would cause deep water upwelling as the currents strike the barrier
the ridge would cause surface water to sink as it piles up against the barrier and has nowhere else to go.

Explanation:

The North Atlantic Gyre is a system of ocean currents. If a barrier (like the hypothetical Mid - Atlantic Ridge in this case) divides the ocean into two compartments, the equatorial and boundary currents would be redirected. The equatorial currents (which are part of the gyre) would be turned north on one side of the barrier, and the northern boundary currents (also part of the gyre) would be turned south on the other side. This redirection would result in the formation of two separate gyres, one on each side of the barrier.

Answer:

The Mid - Atlantic Ridge barrier would turn equatorial currents north and northern boundary currents south, resulting in two gyres, one on each side of the ridge.
