No. It is a layer of rock. The very uppermost layer of the mantle is attached to the crust. The layer directly below it is very plastic-like, yet still considered rock. With increasing depth, the rock of the mantle becomes more and more rigid from increasing lithostatic pressure. The next layer after the mantle is the outer core, which is composed of iron and nickel in a liquid state. Finally, the inner core, solid, an alloy of iron and nickel.
What else can I help you with?
Is the part of the mantle called plates is made of soft rock that bends like plastic right?
The Earth's mantle is made up of solid rock that can deform like a plastic under high temperatures and pressures. Tectonic plates are sections of the Earth's lithosphere (which includes the crust and the upper part of the mantle) that float and move on the underlying semi-fluid asthenosphere. The movement of these plates causes earthquakes, volcanic activity, and the formation of mountain ranges.
Why mantle is known as the plastic mantle?
The mantle is known as the "plastic mantle" because it behaves like a solid near the surface but can flow slowly over time like a very viscous fluid through a process called convection. This plasticity allows the mantle to slowly move and flow, which is one of the driving forces behind plate tectonics and the movement of Earth's lithospheric plates.
Continental plates move on the plastic-like layer of Earth's mantle?
Yes, continental plates move on the semi-fluid layer of Earth's mantle called the asthenosphere. This movement is driven by the convective currents generated by heat from the Earth's core. The interaction between these plates at their boundaries leads to geological phenomena such as earthquakes, volcanic eruptions, and mountain formation.
What is the theory that Earth's crust and upper mantle are broken into plates that float around and move on a plastic like layer of the mantle?
The theory is called plate tectonics. It explains how the Earth's lithosphere is broken into plates that float on the semi-fluid asthenosphere beneath them, causing them to move around and interact at their boundaries, leading to phenomena like earthquakes, volcanoes, and mountain formation.
Why do we call the asthenosphere as the plastic mantle?
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.
Pieces that move on plastic like layer of the mantle?

What do the plates of Earth's crust move on top of?
The layer of the Earth known as the asthenosphere, composed of highly viscous, plastic-like rock located in the upper mantle.

Is lithoshpere a zone in the upper mantle deformed by plastic flowage?
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.
Why do the earths continents float on the liquids mantle of the earth?
The continents "float" on the liquid mantle of the Earth because the metals that make up the mantle are very dense. The continents move when magma is pushed through the crust of the Earth in places like the Mid-Atlantic Ridge.

What is the Soft layer of the upper mantle?
The soft layer of the upper mantle is known as the asthenosphere. It is located just below the lithosphere and is characterized by its ability to flow slowly over time, allowing tectonic plates to move and interact on Earth's surface. This layer plays a crucial role in plate tectonics and the movement of the Earth's crust.
What is the solid plastic layer of the mantle?
The solid plastic layer of the mantle is called the asthenosphere. It is a semi-fluid layer below the lithosphere that allows the tectonic plates to move over it. The asthenosphere is responsible for the movement of the Earth's crustal plates.
Which layer in the geosphere supports the tectonic plates?
The upper layer. It is filled with melted liquid.
