In geology, the places known as hotspots or hot spots are volcanic regions thought to be fed by underlying mantle that is anomalously hot compared with the surrounding mantle. Their position on the Earth's surface is independent of tectonic plate boundaries.
How Hotspot Volcanoes are formed:
Plumes of magma rise from the lower mantle and burn through the Earth's lithosphere to create volanic activity on the Earth's surface. An example of a hotspot Hawaii.The hotspot remains stationary whilst the overlying plate moves.
Explain how a hotspot volcano changes over time as it drifts away from its heat source
The first hotspot in question, is built up by the magma from under the plate’s crust. Then as it more away from the magma heat source, more hotspots are created and the original hotspots starts to decrease in size as it no longer has a heat source. The size is also reduced due to erosion and weathering.
Explain the difference between a hotspot volcano, sea mount, guyot and island chain
