How are hot spots used to track plate movement? - Answers

WebEventually the movement of the tectonic plate carries the volcano off of its magma supply. The volcano becomes extinct and cools. The plate beneath the volcano (and above the hot spot) also cools. The rocks that make the volcano and plate become more dense. The volcano and the plate gradually subside as they move away from the hot spot.

WebIsland arcs. When the downward-moving slab reaches a depth of about 100 km (60 miles), it gets sufficiently warm to drive off its most volatile components, thereby stimulating partial melting of mantle in the plate above the subduction zone (known as the mantle wedge).
