asthenosphere
the plasic like rock of the lower mantle is the asthenosphere
No, the lithosphere is the rigid outer layer of the Earth consisting of the crust and uppermost part of the mantle. It is not deformed by plastic flowage, but rather broken into tectonic plates that can move and interact with each other.
The upper mantle is described as plastic because it can deform and flow slowly over long periods of time, similar to the way plastic deforms under pressure. This property allows the mantle to respond to tectonic forces and play a key role in the movement of Earth's lithospheric plates.
The mantle is divided into the upper mantle, transition zone, and lower mantle. The upper mantle is beneath the lithosphere, the transition zone lies between the upper and lower mantle, and the lower mantle extends to the outer core.
The asthenosphere is often called the plastic mantle because it is a semi-solid layer in the upper mantle that behaves like a plastic material. This means it can flow and deform over long periods of time under pressure, allowing tectonic plates to move slowly over it.
The plastic zone below the upper mantle is called the asthenosphere. It is a semi-fluid layer of the upper mantle where rock can flow like a viscous fluid over long periods of time. The asthenosphere plays a crucial role in the movement of tectonic plates.
The plastic zone is also called the asthenosphere,because in the solid bottom part of the mantle, the temperature is sufficient to make the rock plastic, meaning, it flows.

the upper-mantle rocks are heavier while the lower mantle rocks are semisolid like melted plastic

the plasic like rock of the lower mantle is the asthenosphere
The plastic-like part of the mantle is known as the asthenosphere. It is a semi-fluid layer located beneath the lithosphere, composed of partially molten rock material that allows for the movement of tectonic plates.
The crust moves on a plastic like layer of the mantle.

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.
