What is the difference between Techtonic Plates and Hot spot

Tectonic plates are the pieces of crust that move around Earth's surface, while a hot spot is a point below a tectonic plate that lies just above an area in the mantle that has higher activity.

Explanation:

Tectonic plates are large pieces of crust that float on top of the mantle and move around Earth's surface. They are driven by the convection currents that occur in the mantle, which create big pressure from below, push them in a certain direction, creating different types of interactions between them and contributing to the formation of the vast majority of Earth's landforms and ocean basins.

A hot spot is a place in the mantle that has higher activity than the rest of the mantle. Because of this increased activity, the hot spot is able to penetrate through the crust of the plates, far away from the plate boundaries. The result of it is a hot spot volcano, be it on land or in the ocean. Because the hot spot is static and the plates move, as the plate moves and drags the volcano, it stops with activity, while another is formed just above the hot spot.
