Earth's Crust and Plate Tectonics

The video reviews Earth's layers, focusing on the asthenosphere and crust. It compares oceanic and continental crusts, highlighting their composition and density. The video also covers elements in Earth's crust, such as oxygen and silicon, and explains minerals and their properties. Finally, it introduces different rock types, including igneous, sedimentary, and metamorphic rocks, with examples and characteristics.
