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.

1 sie 2023 · The four main layers of the Earth are the crust, mantle, outer core, and inner core. The Earth, like an onion, consists of several concentric layers, each with its own unique set of properties and characteristics.
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.
The outer core of the earth is bounded by the mesosphere above and the solid inner core below. It is estimated to measure about 1,400 miles thick and it starts about 1,800 miles below the surface of Earth. Unlike other layers of earth, the liquid outer core is completely liquid, through and through.
15 lut 2021 · Mesosphere (or Lower Mantle) This region is a rigid layer between the depths of about 400 to 1800 miles (650 km and 2900 km), but the rocks at these depths are very hot and capable of gradual flow. Heat from the core drives mantle gravitational convection.
Earth is composed of multiple layers, which can be defined either by composition or by mechanical properties. The crust, mantle, and core are defined by differences in composition. The lithosphere, asthenosphere, mesosphere, and outer and inner cores are defined by differences in mechanical properties.
