1 sie 2023 · The four primary layers are the crust, the mantle, the outer core, and the inner core. However, geologists subdivide these layers into a complex structure that better describes the Earth’s intricate composition and behavior. Let’s start with the basic four-layer model before delving into greater detail.
The mesosphere, sometimes known as the lower mantle, is more rigid and immobile than the asthenosphere. Located at a depth of approximately 410 and 660 km below the earth’s surface, the mesosphere is subjected to very high pressures and temperatures.

The Earth has three main layers: the crust, the mantle, and the core. Let's understand these layers with the help of diagrams and structures with 3D models.
Variations in the thickness of the earth’s layers, irregularities in layer boundaries, and interpenetrations of layers, reflect the dynamic nature of the earth. For example, the lithosphere penetrates deep into the mesosphere at subduction zones.
27 wrz 2023 · Because of this, geologists also classify Earth’s interior into five mechanical layers. The mechanical layers are based on movement and strength, and include the lithosphere, asthenosphere, mesosphere, inner core, and outer core.
The mesosphere is the largest part of the mantle and the largest section of the layers of Earth. It is located under the asthenosphere and above the outer liquid ring of the earth’s core. Geologists estimate it starts at around 250 – 410 miles below the surface of the earth.
