Outside the core, the largest mass of planet Earth is called the mantle and this is mostly solid rock. The very outermost layer of our planet is about 30 miles thick, is made of lighter rocks, and is called the crust.
The rigid outer layer of the Earth, called the lithosphere, is made of plates that fit together like a jigsaw puzzle. These plates are made of rock, but the rock is, in general, lightweight compared with the denser, fluid layer underneath. This allows the plates to float on top of the denser material.he rigid outer layer of the Earth, called the lithosphere, is made of plates that fit together like a jigsaw puzzle.
