What are the layers of the earth and what purpose do each of them specifically serve?
In: Earth Science
Most models divide the planet into the core, mantle, and crust. The core may sometimes be separated into inner and outer, with the inner being basically a ball of solid metal and the outer being liquid metal. The core is believed to be responsible for generating the electromagnetic field which protects the planet from solar winds.
The mantle is the large layer of magma. Flows within the magma influence tectonic action on the crust.
The crust is the thin, outermost layer of the planet, originally made from mantle cooled as it radiates heat into space with features changing from tectonic activity as well as weather. It’s where all living things exist.
