Question

Use the diagram to answer each question. Describe an exception to the patterns pictured at A and B where volcanoes also can form.

Answer 1

In the graph, we can see the two most common forms that give rise to volcanoes. Point A represents the generation of a volcano in the submarine bed or ocean floor that, when it erupts, can form islands or abyssal hills. Point B represents the boundary between two tectonic plates because stress cracks form at the pressure edges of two plates. The third case of volcanoes that form far from the limits of the plates is due to the existence of a hot spot in the earth's mantle, whereby heat starts to escape. This case is commonly visible on the island of Hawaii.
