Layers of the Earth Essay

The impertinence is the first and upper most degree of the Earth. There is Continental Crust which sits on top of Oceanic Crust. This form is made frequently from granite rocks and is solid. Continental Crust is approximately 32km. Below the Continental Crust is Oceanic Crust. It is about 8km. This part of the Crust is made from basalt rocks. The Crust is most of lithosphere and is the coolest stage by far.Mantle is like daft putty consistency. It is the largest layer of Earth sitting under the Crust. It is made most from silicon, oxygen, iron, and magnesium. The layer is composed almost entirely of magma molten rock deep down the earth. The cortex is about 2,900km thick. The mantle gets warmer with depth the top of the mantle is about 870 C, headed for the bottom of the mantle, the temperature is about 2,200-3,700 C.outer(a) Core is the third layer. This aim is basically liquid. Most of this layer is made from liquid nickel and iron. Outer Core is about 2,200km thick. The temperature of the Outer Core is 4000-5000C.Inner Core is the quartern layer of the Earth. The thickness of the Inner Core is 1,250km and mainly consists of iron, nickel and roughly lighter elements (probably sulphur, carbon, oxygen, silicon and potassium. The temperature in the inner core is about 5000-6000C, it is the hottest layer of the Earth. Because of the high pressure, the core is solid. If a person were to travel that deep, they would burn up with in the Mantle before they ever came near the core. Even with a ship that could withstand the high temperature, it would be crushed by the broad pressure.
