The Mantle as a Soft Solid
The Mantle as a Soft Solid is a skill on Pengi from Lesson 1: The Mantle and Convection in Amplify Science (California) Grade 7.
Key Concepts
Beneath Earth's rigid outer plates lies a thick layer of rock called the mantle . Understanding the mantle requires understanding a unique state of matter: it is solid rock, but it is not brittle like the crust.
Scientists describe the mantle as a soft solid . Due to immense heat and pressure, the rock in the mantle can deform and flow very slowly, similar to hard wax or silly putty. This property allows the solid mantle to move over geologic time.
