Essential Question: How does Earth's composition change the landscape? Investigation Question: How are Earth's layers formed?
Investigation 1 Claim:
The Earth's layers are formed in the geosphere due to intense heating from radioactive decay at the core and gradual cooling of the mantle moving towards the crust, which is made of the lithosphere and the asthenosphere.
Terms:
Geosphere, Crust, Mantle, Core, Lithosphere, Asthenosphere, radioactive decay, seismic waves
