Earth’s Hidden Interior
Earth’s Hidden Interior is a skill on Pengi from Lesson 1: The Mesosaurus Mystery in Amplify Science (California) Grade 7.
Key Concepts
The ground beneath our feet appears to be soil, sand, or water, but these are just surface coverings. Geologists define Earth's outer layer as a foundation of hard, solid rock that exists everywhere beneath the surface materials.
To understand Earth's history, scientists must look deeper than the soil. They investigate the rock formations underneath. Sometimes, these rocks contain fossils —preserved remains of ancient life—embedded deep within the solid layer, offering clues to the planet's past.
