Mrs. MAA explains plate tectonics, describing how Earth's lithosphere plates move over the asthenosphere due to convection currents. She discusses the effects of plate movement, such as earthquakes and volcanoes, and provides evidence supporting the theory, including fossils and ocean floor spreading. The video covers different plate boundaries and their features, concluding with a discussion on Pangaea.

What does the lithosphere consist of?

• Only the crust

• Crust and upper mantle

• Only the mantle

• Asthenosphere
