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.
Web6. What dohotspot tracksindicate about plate motion? Hotspots are the surface expression of a deep mantle plume and plumes originate far below the lithospheric plates. Plumes are thus nearly stationary and not affected (much) by plate motion. Hotspot tracks thus record the progress of a plate passing over the plume conduit and can provide both ...
