The strong lower part of the mantle is a physical layer called the?
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.
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.
What is the solid plastic layer of the mantle beneath the lithosphere?
The solid plastic layer of the mantle beneath the lithosphere is called the asthenosphere. It is characterized by its semi-fluid nature, allowing for the movement of tectonic plates over time. The asthenosphere plays a crucial role in the process of plate tectonics.
Why is the lower mantle more rigid and dense then the asthenosphere in the upper mantle?
The lower mantle is more rigid and dense than the asthenosphere in the upper mantle because of higher pressure and temperature conditions. The increased pressure in the lower mantle prevents rocks from flowing as easily as in the asthenosphere. This leads to higher density and rigidity in the lower mantle region.
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.
How do upper mantle rock differ from lower mantle rock?
the upper-mantle rocks are heavier while the lower mantle rocks are semisolid like melted plastic
How do upper mantle rocks differ from lower mantle rock?
the upper-mantle rocks are heavier while the lower mantle rocks are semisolid like melted plastic
What is Earth's plastic like layer called?
Earth's plastic-like layer is called the lithosphere. It includes the crust and the uppermost part of the mantle, and it is divided into several tectonic plates that float on the semi-fluid asthenosphere beneath them.
Is there two layers of mantle?
Yes, the Earth's mantle is typically divided into two layers: the upper mantle and the lower mantle. The upper mantle is closer to the Earth's crust and is more rigid, while the lower mantle is deeper and exhibits more plastic-like behavior.
The strong lower part of the mantle is a physical layer called the?
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.
What is the part of the mantle that bend like plastic?
Heat transfer by the movement of a heated fluid is called _________?
What layer of the mantle is most plastic or bendable?
Heat transfer by the movement of a heated fluid is called _________?
What is earth plastic like layer?
mantle
Why do we call the asthenosphere as the plastic mantle?

What is the plastic-like part of the mantle?
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.
What moves on a plasticlike layer of the mantle?
The crust moves on a plastic like layer of the mantle.
What moves a plasticlike layer of the mantle?
The crust moves on a plastic like layer of the mantle.
