The Earth's layers

The video explores the Earth's structure, detailing its four layers: the inner core, outer core, mantle, and crust. The inner core is a solid metal ball, while the outer core is liquid. The mantle is the thickest layer, and the crust is the outermost layer, divided into tectonic plates that move slowly.

What are the four layers of the Earth?

Describe the characteristics of the inner core.

What is the composition of the outer core?

How thick is the mantle layer and how does it compare to the distance between France and Egypt?

Explain the movement of the crustal plates.
