Question

volcanoes form above hotspotmagmahotspotthe san francisco volcanic field is an example of a chain of hotspot volcanoes that formed in arizona. the tallest mountain in arizona, san francisco mountain, is an extinct volcano that is part of this chain of hotspot volcanoes. the most recent volcanic eruption in the volcanic field occurred at sunset crater. figure 3 shows the locations of the san francisco volcanic field, san francisco mountain, and sunset crater.figure 3. san francisco volcanic fieldncalifornia arizonasan francisco volcanic fieldsunset cratersan francisco mountainbased on figure 2, which statement correctly explains how a hotspot forms a chain of volcanoes?a. a hotspot increases its size over time to produce large volcanoes.b. a hotspot pushes older volcanoes away to make space for new volcanoes.c. the matter from older volcanoes is absorbed by a hotspot and used to build the next volcano.d. the movement of matter below a plate causes both older volcanoes away from a hotspot.

Explanation:

Hotspots are stationary plumes of magma beneath the Earth's crust. As the tectonic plate (lithosphere) moves over the stationary hotspot, the older volcanoes carried by the plate move away from the magma source, and new volcanoes form above the hotspot, creating a chain. The correct statement describes this plate movement relative to the fixed hotspot.

Answer:

The movement of matter below a plate causes both older volcanoes away from a hotspot.
