Layers of the Earth: Chemical Composition and Physical Properties

This video from MooMooMath and Science explores the layers of the Earth based on chemical composition and physical properties. It describes the crust, mantle, and core, detailing their characteristics and composition. The crust is divided into continental and oceanic types, while the mantle is a region of hot, slow-moving solid rock. The core, composed mainly of iron and nickel, is the densest layer. The video also explains the Earth's layers based on physical properties, including the lithosphere, asthenosphere, and mesosphere. The video concludes with a call to subscribe for more educational content.
