  1. 1

    The Earth's crust is divided into two types: continental crust, which is felsic and thick, and oceanic crust, which is mafic and thin.

  2. 2

    The mantle is a solid but malleable layer mainly composed of peridotite, and it convects, transferring heat to the surface.

  3. 3

    Earth's magnetic field is generated by the geodynamo in the liquid outer core, and the solid inner core helps stabilize this field.
