Lithosphere

The video explains the structure of the lithosphere, highlighting the differences between the crust and upper mantle compared to the lower mantle and core. It describes how the lithosphere is divided into tectonic plates, which move due to convection currents in the mantle. The video also compares the thickness of oceanic and continental lithospheres.

What role do convection currents play in the movement of tectonic plates?
