Earth Interior

Earth Interior is a part of the earth beneath the crust

Lithosphere is the outer part of the earth

Hydrosphere is the waters of the earth’s surface

Atmosphere is mass of air surrounding the earth

Layers

Oceanic Crust is land underneath the ocean

Continental Crust is rocky outer layer of Earth

Mantle is thick layer and is made up of melted rock

Outer Core is 2,250 km thick and is completely liquid

Inner Core is solid and is made up of nickel and iron

Summary

There are three major types of the earth interior types: atmosphere, hydrosphere, lithosphere.

Earth is divided in different parts called layers. Outer layer of the earth has continental and oceanic layers. Underneath these crusts there’s a mantle, liquid magma. Underneath the mantle there’s a outer core, total liquid. Mantle and outer core are both liquid but they never mix. And last deepest layer is inner core and is solid made of metal.

Continental Drift

Continental Drift is a theory that all the continents had formed one landmass before breaking apart and drifting to their present locations.

This landmass was called Pangea. The theory

was brought by Alfred Wegener in 1915.
