summer school hw question?

halfway evacuated due to a fairly recent volcanic eruption. Why is there a volcano on this island?

a. The Caribbean oceanic crust is extremely thin allowing the internal

heat from the Earth to escape in the form of volcanoes.

b. Montserrat is located on a plate that is moving over a deep Hot Spot

located in the mantle.

c. Montserrat is located on a very unstable plate prone to cracking and

releasing subsurface magma.

d. A portion of the North American plate is being subducted under the

Caribbean Plate creating the melting of the Earth’s mantle and

generation of rising magma.
