How do hot spots form volcanic islands?

Hot spots form volcanic islands when a tectonic plate moves over a stationary mantle plume. The heat from the mantle plume causes melting of the overlying plate, leading to the formation of magma. This magma rises to the surface, creating a volcanic eruption and eventually forming a volcanic island. As the tectonic plate continues to move, the volcanic island moves away from the hot spot, and a new island may form in its place.
