The Earth, like an onion, consists of several concentric layers, each with its own unique set of properties and characteristics. The four primary layers are the crust, the mantle, the outer core, and the inner core.

To really understand Earth, you need to travel 6,400 kilometers (3,977 miles) beneath our feet. Starting at the center, Earth is composed of four distinct layers. They are, from deepest to shallowest, the inner core, the outer core, the mantle and the crust.

The internal structure of Earth are the layers of the Earth, excluding its atmosphere and hydrosphere. The structure consists of an outer silicate solid crust, a highly viscous asthenosphere, and solid mantle, a liquid outer core whose flow generates the Earth's magnetic field, and a solid inner core.

Learn how the Earth is divided into four layers based on composition, temperature, and structure. Find out the characteristics, features, and functions of each layer, and how they affect the Earth's surface and environment.

The Earth’s interior can be divided into three main layers: the crust, the mantle, and the core. These layers have distinct properties and compositions, which play a significant role in shaping our planet’s geology and behavior.

Our planet consists of several layers, each playing a vital role in Earth’s overall structure and function. From the core, nestled deep within Earth’s center, to the mantle and the crust that forms the surface we live on, understanding these layers provides valuable information about the geological processes that have shaped our planet.

In this article, we’ll unwrap each layer of the earth, from the outermost layer called the crust, to the innermost layer, the inner core. Our discussion topics will include an analysis of the earth’s layers from two perspectives: the chemical layers and the physical layers.

Physical layers include the lithosphere and asthenosphere; chemical layers are crust, mantle, and core.

The inner core, the outer core, the mantle and the crust are the four layers of the earth.
