Earth Interior is a part ofthe 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
LayersOceanic Crust is land underneath the oceanContinental Crust is rocky outer layer of EarthMantle is thick layer and is made up of melted rockOuter Core is 2,250 km thick and is completely liquidInner Core is solid and is made up of nickel and iron
SummaryThere are three major types of the earth interior types:atmosphere, hydrosphere, lithosphere.Earth is divided in different parts called layers. Outerlayer of the earth has continental and oceanic layers.Underneath these crusts there’s a mantle, liquidmagma. Underneath the mantle there’s a outer core,total liquid. Mantle and outer core are both liquid butthey never mix. And last deepest layer is inner core andis solid made of metal.
