Khan Academy
Structure of the Earth
Salman Khan delves into the layers of the Earth. He provides names and general numbers about depths and composition.
Khan Academy
Plate Tectonics: Geological Features of Divergent Plate Boundaries
Sal explains the mechanism of crust lift developing at hot spots. The density changes at that point, continuing to cause depressions. The depressions and thinner layers fill with water, resulting in a flooded rift valley.
Khan Academy
Plate Tectonics: Difference Between Crust and Lithosphere, Cosmology and Astronomy
Explore the tectonic plates that make up the surface of our Earth and their movement, as well as the terminology of the Earth's structure.
