Journey to the Center of the Earth

This is the first part of our understanding of our Mother Earth — its interior. We learn that the Earth has four main layers: the crust, mantle, outer core, and inner core. As you watch, write observational notes about what you may find inside. Pay careful attention to the numbers and the data.

Struggling to make sense of the Earth’s layers, think of an apple. It has a skin, flesh, core, and seeds.
