Lithosphere and Tectonic Plates

This video from MooMooMath and Science explains the lithosphere, the solid outer layer of Earth, which includes the crust and upper mantle. It describes the two types of lithosphere: oceanic, which is denser and found in ocean basins, and continental, which is thicker and found on land. The video also covers tectonic plates, their movement, and the historical supercontinent Pangaea. It concludes with a discussion on how tectonic plate movements cause earthquakes.

What is the lithosphere composed of?

• Only the crust

• Only the mantle

• The entire mantle

• The crust and the upper part of the mantle

Which part of the Earth does the lithosphere represent?

• The middle layer

• The innermost layer
