What name is given to the plastic portion of the upper mantle of the Earth?
The plastic portion of the upper mantle of the Earth is known as the asthenosphere. It is a semi-fluid layer beneath the lithosphere that allows tectonic plate movement.
Is the upper mantle part of the lithosphere or asthenosphere?
The The crust and the uppermost layer of the mantle form the lithosphere. The asthenosphere, which is still in the upper mantle, is the next layer down.
What does the term plastic mean when describing the upper mantle?
When describing the upper mantle, the term "plastic" refers to the ability of the mantle material to deform and flow over long periods of time under high temperatures and pressures. This plastic behavior allows the mantle to flow and convect, driving plate tectonics and other geological processes.
Why is the upper mantle described as plastic?
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.
What is the moving portion of earths crust and upper mantle?
The moving portion of Earth's crust and upper mantle is known as the lithosphere. It is broken into tectonic plates that float on the semi-fluid asthenosphere below, causing them to move and interact with each other, which leads to processes like earthquakes, volcanic eruptions, and mountain building.
What name is given to the plastic portion of the upper mantle of the Earth?
The plastic portion of the upper mantle of the Earth is known as the asthenosphere. It is a semi-fluid layer beneath the lithosphere that allows tectonic plate movement.
What part of the mantle is made of soft rock that bends like plastic.?
A portion of the upper mantle known as the asthenosphere.
Which portion of the mantle is more plastic?
The upper mantle is more plastic compared to the lower mantle. This is because the upper mantle is closer to the Earth's surface, which allows for more pressure release and higher temperatures, making the rock more ductile and capable of flow.
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
What portion of the mantle is more plastic?
lower
Is the lower portion of the crust and the upper portion of the mantle called the core?
No, the lower portion of the crust and the upper portion of the mantle together are not called the core. The core is a separate layer found beneath the mantle, and it is divided into the outer core and inner core based on composition and properties.
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
Is the upper mantle part of the lithosphere or asthenosphere?
The The crust and the uppermost layer of the mantle form the lithosphere. The asthenosphere, which is still in the upper mantle, is the next layer down.
Are tectonic plates made of mantle?
The solid portion of the upper mantle which behaves as a brittle solid is known as the lithospheric mantle. This part of the upper mantle along with the crust forms tectonic plates.
What do geologists believe heats the upper mantle portion of the asthenosphere?
sososkssososossmsmsm
What is the crust and brittle upper mantle called?
Earth's crust and brittle upper mantle is called the lithosphere.
What are molten material in the mantle?
Yes. The mantle is composed of the plastic mantle, or the upper part, which is partially molten. The stiffer mantle is under it. it is not as molten
