The asthenosphere.
The lower boundary of the asthenosphere is not well defined. It lies below the lithosphere and above the lower mantle and outer core. It usually lies at depths of 80-200 km but can range as deep as 700 km.
The transition zone between the asthenosphere and the crust is called the lithosphere. It is the rigid outer layer of the Earth that consists of the crust and the uppermost part of the mantle. The lithosphere is broken into tectonic plates that float and move on the semi-fluid asthenosphere beneath it.
The zone you are referring to is the mesosphere, which lies between the base of the asthenosphere and the boundary separating the mantle from the core. It is characterized by high pressure and temperature conditions, as well as the gradual increase in density from the bottom of the mantle to the core-mantle boundary.
The plastic-like zone in the mantle is known as the asthenosphere. It is a semi-fluid layer located beneath the lithosphere, where rock can flow slowly under stress. The asthenosphere plays a crucial role in plate tectonics by allowing the movement of tectonic plates.
One characteristic of the asthenosphere is that it is a semi-fluid layer beneath the lithosphere where the material can flow slowly over time. This property allows for the movement of tectonic plates.
The rigid zone above the asthenosphere that includes the crust and upper mantle is called the lithosphere. This layer is divided into tectonic plates that float on the semi-fluid asthenosphere and move due to the convection currents beneath them.
The asthenosphere.
The plastic-like layer below the lithosphere is called the asthenosphere. It is partially molten and allows the rigid lithosphere above it to move and drift on the flowing asthenosphere, causing tectonic plate movement.
The lower boundary of the asthenosphere is not well defined. It lies below the lithosphere and above the lower mantle and outer core. It usually lies at depths of 80-200 km but can range as deep as 700 km.
a region where oceanic plates sink down into the asthenosphere is called a subduction zone.

The plastic-like zone in the mantle is known as the asthenosphere. It is a semi-fluid layer located beneath the lithosphere, where rock can flow slowly under stress. The asthenosphere plays a crucial role in plate tectonics by allowing the movement of tectonic plates.
The layer directly below the lithosphere is the asthenosphere. The asthenosphere is partially molten and allows for the movement of tectonic plates above it.
