Plate Tectonics Evidence
Plate tectonics is the theory that Earth's outer shell is divided into several plates that glide over the mantle, the rocky inner layer above the core.
the formation of new areas of oceanic crust, which occurs through the upwelling of magma at midocean ridges and its subsequent outward movement on either side.

Hot spots are not close to plate boundaries like most volcanoes, which leads scientists to believe the the hot spot stays in one place while the plate moves over it.
