What layers of the earth does our earth consist of?

The earth consists of different layers, which, in turn, consist of different materials, different in composition, weight, density. The deeper inside the globe, the denser the layer. Consider the layers from deep to surface:

1. Inner core – located in the very center of the Earth. It has a solid structure with a thickness of more than 5000 km and a temperature of 7000 ° C. Consists of iron and nickel.

2. Outer core – has a liquid structure of the same metals as the inner core. The layer is about 5000 km thick and the temperature is 5000 ° C.

3. The mantle is the widest layer. Has a total thickness of about 2900 km. The mantle is divided into:

– the upper part has a solid structure.

– the lower part (asthenosphere) – a viscous structure. It lies at a depth of 150 km under the continents and 15-150 km under the oceans.

4. The Earth’s crust is the topmost layer. It is a thin layer of hard rocks. We go deeper about 32-48 km under the continents and 5-8 km under the oceans. It contains potassium, aluminum, calcium, silicon, sodium.
