Hot spot definition plate tectonics
WebThe hot spot doesn't move, but the crust above the hot spot does. This results in a line of volcanoes being burned into the crust, with only the volcano directly over the hot spot being active. Because hot spots remain in place they can be used to tell the direction of plate motion in the past, as well as how fast the plates were moving. WebReference Lists.
