Layers of the Earth. The earth is made up of layers (crust, mantle, outer core, and inner core). Each one has a unique make-up to it. Crust. This is the outer layer of the Earth about 10 miles or so thick. Mostly made up of rock and loose material.The crust found underneath continents is 3 times thicker than the crust underneath the oceans.he first 50 miles of the mantle are believed to consist of very hard rigid rock. The next 150 miles or so is believed to be super-heated solid rock. Below that for the next several hundred miles, the Earth mantle is once again made up of very solid and sturdy rock materials.
