Tectonic Plates

The video explains the Earth's lithosphere, which is the upper layer of the mantle bonded to the crust. It describes how the lithosphere is divided into tectonic plates that move slowly but dynamically over a fluid layer beneath. These movements cause the plates to crack, creating rifts and subduction zones. The video highlights the formation of rifts like the Red Sea and the creation of mountains and volcanoes through subduction, where oceanic and continental plates meet.
