Question

Help me please!! I don’t know

Answer 1

A. Volcanoes, Mid Ocean Ridge
B. Volcanoes form at convergent boundaries, when one plate is being pulled under the other. Mid ocean ridges form at divergent boundaries in the bottom of the ocean where the two plates are pulling apart from each other and magma comes up from the mantle to create an underwater mountain range.

Answer 2

Large mountains such as Mount Everest were caused by plates colliding together at a fast rate, however something like the Hawaiian Islands were formed by a hot spot occurring in the middle of the Pacific Plate. While the hot spot itself is fixed the plate is in a constant but slow rate of movement. So, as the plate moved over the hot spot the group of islands known as the Hawaiian Island chain were formed. The largest Island being the most recently active and the smaller islands eroding are due to many years of inactivity as they move away from the hot spot.
