Hot spot (geology)

Episode 9 of Plate Tectonics delves into hot spots, volcanic regions distinct from plate boundaries. Building upon our understanding of plate tectonics, continental drift, seafloor spreading, subduction, and mantle convection, we will explore the origin and characteristics of hot spots. We will examine how hot spots create volcanic island chains and provide evidence for plate movement. This episode will enhance your understanding of volcanic activity and the dynamic processes occurring deep within the Earth.
