Inner Core: solid, mostly Iron and Nickel, temperature up to about 13,000°F (7,200°C = 7,500 K), radius of about 750 miles (1,228 km).
Outer Core: molten, about, mostly Iron and Nickel, 1,400 miles (2,260 km) thick. temperature about 3600 degrees C
Lower Mantle: composed of silicon, oxygen, magnesium, iron, aluminum, and calcium. The lower mantle flows slowly, at a rate of a few centimeters per year. towards the bottom of the mantle, the temperature is about 4,000-6,700° F (2,200-3,700° C).
Upper Mantle: composed of silicon, oxygen, magnesium, iron, aluminum, and calcium. The mantle is about 1,700 miles (2,750 km) thick. The mantle gets warmer with depth; the top of the mantle is about 1,600° F (870° C);
Crust: The Earth's thin, rocky crust is composed of silicon, aluminum, calcium, sodium and potassium. The crust is thinner under the oceans (6-11 km thick). 31.15 km thick on average. Temperature: ~ 15 C (average on surface)
Inner Core.The Crust, oxygen, silicon, aluminum, iron, calcium, magnesium, potassium and sodium. It is divided into huge plates that float on the mantle, which is in the next layer. its about 25 miles thick, and there is really not a average temp.
The Mantle, is a silicate rocky shell about 1,802 miles thick.
Outer Core, composed of mostly iron and nickel that lies above Earth's solid
inner core its about 1400 miles thick. its temps are between 44000 F and 66000 F
Inner Core. temp is about 100000 F and 1250 km thick. is is highly compact rock and medles
