What tectonic setting is interpreted to be the cause of volcanism at Yellowstone?

A) subduction along the coast of the Pacific Northwest
B) magma that is coming up along a bend in a transform fault
C) movement of North America over a mantle plume
D) a large meteorite impact that struck the area 100 years ago

Mantle Plume

A narrow, ascending column of hot, solid material from the deep mantle that can create hotspots and volcanic activity at the Earth's surface.

Subduction

The process by which one tectonic plate moves under another, diving into the earth’s mantle, often causing volcanic activity and earthquakes.

Transform Fault

A type of fault where two tectonic plates slide past one another horizontally, often causing earthquakes.
