Earth's Layers and Properties

The video introduces the Earth's layers, created by Nway Fang and narrated by Shan Kupa, as part of Ohio University's project funded by NSF. It explains the Earth's crust, mantle, outer core, and inner core, detailing their composition, thickness, and properties. The video also discusses the density of these layers and concludes with a summary of the Earth's complex structure.
