Core
The mesosphere
It's called the lower mantle.
the lithosphere is the full crust and top part of the mantle but the asthenosphere is just a little bit above the middle of the mantle but not any of he crust
The lower part of the mantle is called the "lower mantle" or "mesosphere", while the upper part of the mantle is referred to as the "upper mantle" or "asthenosphere".
The partly melted, plastic-like rock of the Earth's lower mantle is known as the "asthenosphere." This layer, located beneath the lithosphere, is composed of semi-solid rock that can flow slowly over geological time scales. Its plasticity allows for the movement of tectonic plates above it, playing a crucial role in plate tectonics.
the plasic like rock of the lower mantle is the asthenosphere
The lower part of the mantle is called the mesosphere.
The strong lower part of the mantle is called the lower mantle. This region extends from 670 km to 2,900 km below the Earth's surface and exhibits solid-like properties due to high pressure and temperature conditions present.
The mantle is subdivided into the upper mantle and the lower mantle. The upper mantle is closer to the Earth's surface and consists of solid rock that can flow slowly over long periods of time. The lower mantle is located beneath the upper mantle and is more rigid due to higher pressure and temperature.
the lithosphere
The lower part of the mantle in Earth's crust is called the lower mantle. It lies beneath the upper mantle and extends from about 670 to 2,900 kilometers below the Earth's surface. It is composed of solid rock that can flow slowly over very long periods of time.
The strong lower part of the mantle between the asthenosphere and the outer core is called the lower mantle. The layer of the atmosphere between the stratosphere and the thermosphere is called the mesosphere.
