   • Crust. Temperature: 475 K (∼200°C) at the surface to 1300 K (∼1000°C) Thickness: 25 miles (32 km) for continental crust and 3-5 miles (8 km) for oceanic crust.
   • Upper Mantle. Temperature: 1200 K (∼ 932°C) at the upper boundary with the crust to 1900 K (∼1652 °C) at the boundary with the lower mantle. Thickness: 255 miles (410 km)
   • Lower Mantle. Temperature: 1900 K (∼ 1600°C) in the outer regions which can reach up to 4300 K (∼4000°C) at the bottom. Thickness: 1,400 miles (2,250 km)
   • Outer Core. Temperature: 4,300 K (4,030°C) in the outer regions to 6,000 K (5,730°C) closest to the inner core. Thickness: 1,355 miles (2,180 km) Density: 9,900 – 12,200 kg/m3.

   • The inner core, the outer core, the mantle and the crust are the four layers of the earth.
   • The Inner Core is the centre and the hottest layer of the Earth.
   • The Outer Core comprises metals such as iron and nickel.
   • The temperature of the Outer Core of the Earth is around 4000 o F to 9000 o F.
   • Mantle is the widest section of the Earth. Its thickness is approximately 2,900 km.

   Are there 8 layers of Earth?

   • No, there are not eight layers of the Earth. Earth is made up of four distinct layers: the inner core, the outer core, the mantle, and the crust. The inner core is the deepest layer and has a solid inner core and a liquid outer core with a temperature range of 4400 °C to 6100 °C (7,952 °F to 11,012 °F).
