Question

multiple choice question
what is a system of mountain ranges on the seafloor separated by valleys called?
o mid - ocean ridge
o rift valley
o hot spot

Explanation:

A mid - ocean ridge is a system of mountain ranges on the seafloor. It is formed by tectonic plate movement at divergent boundaries. The ridges are underwater mountain chains, and the valleys that separate parts of the mid - ocean ridge are called rift valleys. A hot spot is a location where magma from deep within the mantle rises to the surface, creating volcanic activity, and it is not a system of mountain ranges on the seafloor separated by valleys in the same sense as a mid - ocean ridge.

Answer:

mid - ocean ridge
