What Is The Relationship Between The Mantle And The Lithosphere??


What Is The Relationship Between The Mantle And The Lithosphere??

The lithosphere includes the brittle upper portion of the mantle and the crust, the outermost layers of Earth’s structure. It is bounded by the atmosphere above and the asthenosphere (another part of the upper mantle) below. Although the rocks of the lithosphere are still considered elastic, they are not viscous.May 20, 2015

What is the relationship between the crust mantle lithosphere and asthenosphere quizlet?

The relationship between the Lithosphere, Asthenosphere, and Mesosphere is the lithosphere contains the tectonic plates, the Asthenosphere the plates move on top of them, and the Mesosphere convection currents move in this layer help drive the plates in the Lithosphere. Based on the Physical properties.

What are the relationships between the mantle crust asthenosphere and lithosphere?

The lithosphere is the brittle crust and uppermost mantle. The asthenosphere is a solid but it can flow, like toothpaste. The lithosphere rests on the asthenosphere.

What is the relationship between plates and the lithosphere?

Tectonic plates, large slabs of rock that divide Earth’s crust, move constantly to reshape the Earth’s landscape. The system of ideas behind plate tectonics theory suggests that Earth’s outer shell (lithosphere) is divided into several plates that glide over the Earth’s rocky inner layer above the soft core (mantle).

What is the relationship between the mantle and the core?

Convection currents within Earth’s mantle form as material near the core heats up. As the core heats the bottom layer of mantle material, particles move more rapidly, decreasing its density and causing it to rise.

What is the main difference between the lithosphere and the asthenosphere contrast the oceanic lithosphere and continental lithosphere?

The oceanic lithosphere consists mainly of mafic crust and ultramafic mantle and is denser than the continental lithosphere, for which the mantle is associated with a crust made of felsic rocks.

What’s the difference between the lithosphere and asthenosphere?

The lithosphere (litho:rock; sphere:layer) is the strong, upper 100 km of the Earth. The lithosphere is the tectonic plate we talk about in plate tectonics. The asthenosphere (a:without; stheno:strength) is the weak and easily deformed layer of the Earth that acts as a “lubricant” for the tectonic plates to slide over.

Which of the following correctly describes the relationship between lithosphere and asthenosphere?

Q. Which of these describes the lithosphere and the asthenosphere? The lithosphere is rigid and immovable, and the asthenosphere is hot and flowing.

What is the difference between the mantle and the lithosphere?

The Layers of the Earth

The mantle is the intermediate layer of the Earth and can be subdivided into the inner and outer mantle. Most of the mantle is a thick fluid that moves in currents, but the very outermost portion of the outer mantle is solid. This portion and the solid crust make up the lithosphere.

What area of the mantle does the lithosphere float on?

the asthenosphere
Lithospheric plates float on the uppermost part of the mantle called the asthenosphere. The asthenosphere is made up of solid rocks that become…

What causes the lithosphere to be divided into different plates?

Plate Tectonics

The lithosphere is divided into huge slabs called tectonic plates. The heat from the mantle makes the rocks at the bottom of lithosphere slightly soft. This causes the plates to move. The movement of these plates is known as plate tectonics.

What makes up the lithosphere?

The lithosphere is the rocky outer part of the Earth. It is made up of the brittle crust and the top part of the upper mantle. The lithosphere is the coolest and most rigid part of the Earth.

Which statement correctly describes the relationship between Earth’s mantle and its crust?

Question: Which statement correctly describes the relationship between Earth’s mantle and its crust? New crust is formed by magma rising from the mantle in some places, and old crust is pushed back down into the mantle in other places. The crust sits motionless on top of the mantle and does not interact with it.

What explains the relationship between Earth’s mantle and outer core?

Cooler materials move from Earth’s mantle to the lithosphere. Cooler materials are highly dense, causing them to sink to the outer core. Warmer materials sink to the mantle because their density slowly decreases.

What does the plate tectonic theory explain about the lithosphere of the earth?

The theory of plate tectonics states that the Earth’s solid outer crust, the lithosphere, is separated into plates that move over the asthenosphere, the molten upper portion of the mantle. Oceanic and continental plates come together, spread apart, and interact at boundaries all over the planet.

How are the lower mantle and the asthenosphere different?

Below the Moho, the mantle is characterized by peridotite, a rock mostly made up of the minerals olivine and pyroxene. The asthenosphere is the denser, weaker layer beneath the lithospheric mantle. … The asthenosphere is much more ductile than either the lithosphere or lower mantle.

How does the lithosphere differ from the asthenosphere quizlet?

The lithosphere differs from the asthenosphere because the lithosphere is the solid outer layer of the earth and the asthenosphere is below the mantle and made of slow flowing rock. You just studied 56 terms!

Is the asthenosphere the same as the upper mantle?

Characteristics. The asthenosphere is a part of the upper mantle just below the lithosphere that is involved in plate tectonic movement and isostatic adjustments. … The upper part of the asthenosphere is believed to be the zone upon which the great rigid and brittle lithospheric plates of the Earth’s crust move about.

What makes up the lower mantle?

composition of Earth’s interior

(1,800 miles), consists of the lower mantle, which is composed chiefly of magnesium- and iron-bearing silicates, including the high-pressure equivalents of olivine and pyroxene.

What are the similarities between lithosphere and asthenosphere?

Both the lithosphere and asthenosphere are part of Earth and are made of similar material. Lithosphere is made up of Earth’s outermost layer, the crust, and the uppermost portion of the mantle. In comparison, the asthenosphere is the upper portion of Earth’s mantle (which is also the middle layer of Earth).

What are some similarities and differences between the lithosphere and the crust?

Comparison of the Lithosphere and Asthenosphere
Lithosphere Asthenosphere
Lithosphere is composed of the crust and upper most solid mantle Asthenosphere is composed of the upper most weaker part of the mantle
Lies beneath the atmosphere and above the asthenosphere Lies beneath the lithosphere and above the mesosphere

What is the difference between crust and lithosphere include in your answer both where they are located and what their properties are?

The crust is thin, brittle, rigid layer on the Earth’s surface that is made of rock. The lithosphere is also brittle and rigid but it is thicker; it includes the crust and upper most mantle and is about 100 km thick.

What is lithosphere in short answer?

Lithosphere is the solid crust or the hard top layer of the earth. It is made up of rocks and minerals. It is covered by a thin layer of soil. It is an irregular surface with various landforms such as mountains, plateaus, desert, plains, valleys, etc.

Why does the lithosphere float on the mantle?

The continental and oceanic crusts sit on a thick layer of solid rock known as the mantle. … They drift because they are sitting on a layer of solid rock (the upper mantle or “asthenosphere”) that is weak and ductile enough that it can flow very slowly under heat convection, somewhat like a liquid.

What does the lithosphere float on?

In effect, the lithosphere floats on the asthenosphere “carrying” the lithospheric plates that are constantly changing position.

Is lithosphere and crust the same thing?

The lithosphere is the rigid outer layer of the Earth required by plate tectonic theory. … The lithosphere includes the crust (whether continental or oceanic) and the uppermost part of the upper mantle.

Is made of earth crust and upper mantle It is subdivided into portions called?

Earth’s lithosphere. Earth’s lithosphere, which constitutes the hard and rigid outer vertical layer of the Earth, includes the crust and the uppermost mantle.

How is lithosphere formed Class 9?

Due to the cold temperature of space, the surface layer of earth cooled off quickly. … And forms solidified “outer layer of the earth” called lithosphere. Differentiation of magma makes two types of “lithosphere, oceanic” and continental which is characterized in the continents by “basalt in oceans” and granite.

What are the three main processes that change the lithosphere?

Lithospheric Processes cause magmatism, mantle dynamics, and faulting, which in turn shape the Earth’s ever-changing surface.

Which one of the following describe the lithosphere upper and lower mantle crust and upper mantle crust and core mantle and core?

The crust and top upper part of the mantle is called lithosphere. … Upper and lower mantle is the complete range of mantle and is not called lithosphere. They are a part of the layers of the mantle, while lithosphere is composed of the crust and the top upper part of the mantle.
