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.

∙ 15y ago"Plastic" perfectly describes the molten rock in the mantle. The word means that the rock is soft and flexible. When a person talks about "plastic" in common usage, they are referring to polymers such as polyethylene and polystyrene. No ordinary polymer can survive the temperatures in the mantle.

Continental plates move on the plastic-like layer of Earth's mantle?
Asthenosphere
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?
It is the theory of plate tectonics.
What caused the continental plate to move?
The Earth's plates are lighter than the mantle. The top layer of the mantle is almost plastic in it's ability to bend and move without breaking. Heat from the interior of Earth appears to rise in currents through the mantle. The crustal plates ride on these currents as new crust is created at the mid-ocean ridges, and destroyed at oceanic trenches.
How convection currents in the earth's mantle move?
They move because of the heat from the outer core and the mantle.
The driving forces of tectonic plates are related to convection currents in Earth's?
mantle.

Pieces that move on plastic like layer of the mantle?
crust
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.

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.

The zone below the lithosphere it is more plastic than the lithosphere so it is easier to bend and move?
The zone below the lithosphere is the mantle. Convection currents occur here because of the magnetism in the Earth. It is somewhat plastic like.
What causes earth 's plates to move continuously?
Convection in the earth's mantle.
What part of the earth's interior do the plates move on?
The outer mantle
How convection currents affect the plates?
The rock of the upper mantle known as the asthenosphere is plastic-like but not molten. It acts like a conveyor belt, moving heat from Earth's interior upward, and cooled material downward in a big loop. New crust is created where mantle material reaches the surface at places called mid-ocean ridges. Older, colder oceanic crust is subducted and drawn into the mantle, completing the loop.
The driving forces of tectonic plates are related to convection currents in Earth's?
mantle.
