The Crust is the first and upper most bed of the Earth. There is Continental Crust which sits on top of Oceanic Crust. This bed is made often from granite stones and is solid. Continental Crust is about 32km. Below the Continental Crust is Oceanic Crust. It is about 8km. This portion of the Crust is made from basalt stones. The Crust is most of lithosphere and is the coolest bed by far.

Mantle is like cockamamie putty consistence. It is the largest bed of Earth sitting under the Crust. It is made approximately from Si. O. Fe. and Mg. The bed is composed about wholly of magma – molten stone inside the Earth. The mantle is about 2. 900km midst. The mantle gets warmer with deepness ; the top of the mantle is about 870° C. headed for the underside of the mantle. the temperature is about 2. 200-3. 700° C.

Outer Core is the 3rd bed. This degree is fundamentally liquid. Most of this bed is made from liquid Ni and Fe. Outer Core is about 2. 200km midst. The temperature of the Outer Core is 4000-5000°C.

Inner Core is the 4th bed of the Earth. The thickness of the Inner Core is 1. 250km and chiefly consists of Fe. Ni and some lighter elements ( likely sulfur. C. O. Si and K. The temperature in the inner nucleus is about 5000-6000°C. it is the hottest bed of the Earth. Because of the high force per unit area. the nucleus is solid. If a individual were to go that deep. they would fire up with in the Mantle before they of all time came near the nucleus. Even with a ship that could defy the high temperature. it would be crushed by the great force per unit area.
