Internal Structure of the Earth

The internal structure of the Earth is composed of several layers, each with its own unique properties and characteristics.

1. Crust: - The Earth's crust is the outermost layer and is composed of solid rock. It is the thinnest layer of the Earth, ranging from 5 to 70 kilometers in thickness. - The crust is divided into continental and oceanic crust, with the continental crust being thicker and less dense than the oceanic crust. - Source:

2. Mantle: - Beneath the crust lies the mantle, which is a thick layer of solid rock that extends to a depth of about 2,900 kilometers. - The mantle is composed of silicate rocks and is divided into the upper mantle and the lower mantle. - The upper mantle is rigid, while the lower mantle is under high pressure and temperature, causing the rock to flow slowly over geological timescales. - Source: 3. Outer Core: - Below the mantle is the outer core, which is a liquid layer composed of iron and nickel. - The outer core is in a state of constant motion, and the flow of metallic liquids in this layer generates the Earth's magnetic field through the dynamo effect. - Source: [[3]](https://ru.wikipedia.org/wiki/%D0%A1%D1%82%D1%80%D0%BE%D0%B5%D0%BD%D0%B8%D0%B5_%D0%97%D0%B5%D0%BC%D0%BB%D0%B8)

4. Inner Core: - At the center of the Earth lies the inner core, which is a solid sphere composed primarily of iron and nickel. - The inner core is under immense pressure, causing the iron and nickel to be in a solid state despite the high temperatures. - Source: In summary, the Earth's internal structure consists of the crust, mantle, outer core, and inner core, each with distinct properties and compositions.
