The Four Layers Of The Earth. Explore Earth's hidden layers beneath our feet. Because of this, the crust is made of the lightest materials (rock- basalts and granites) and the core consists of heavy.

The top layer is the one we live on, and it's called the crust. A video created as a small project for my Earth Science class.
Each layer has its own properties, composition, and characteristics that affects many of the key processes of our planet.
What would you find if you dug a hole thousands of miles deep?
