Earth's Spheres

Starting with the core, Earth is made up of six ever-increasing concentric spheres. The Earth’s Spheres series examines these layers one at a time, discussing how we know what we do about them, what they tell us of the history of our planet, and how the spheres interrelate with each other to sustain life.
