What is the asthenosphere and lithosphere?

Concept Sketch Lithosphere vs Asthenosphere.pdf -. School University of Wisconsin, Milwaukee. Course Title GEOLOGY 100. Uploaded By JudgeRamPerson470. Pages 1.

Why do earthquakes occur in the asthenosphere?

Lithosphere and asthenosphere have the same physical properties; they are both rigid. Response Feedback: FEEDBACK: The lithosphere is rigid while the asthenosphere is more fluid. Both lithosphere and asthenosphere are compositionally similar, but the asthenosphere is the mantle material that is warmer (not cooler) than 1,280°C. Question 26 2 out of 2 points (Q017) The …

What is the lithosphere made of?

Identify statements true of the lithosphere and asthenosphere. a. The asthenosphere underlies the lithosphere. b. c. The asthenosphere is relatively soft compared to the rigid lithosphere. 6. Order the steps of volcanic island arc formation. a.

Is the lithosphere brittle or rigid?

Definition Asthenosphere-layer below the lithosphere, made of a portion of the upper mantle; the asthenosphere can flow. Core-the innermost, densest layer of a celestial body; Earth's metallic core has an inner solid layer and an outer layer of liquid metal; the sun's core is where nuclear fusion takes place.

What and where are the lithosphere and the asthenosphere?

The Lithosphere is composed of the crust and upper most solid mantle. While the Asthenosphere, which lies beneath the lithosphere, is composed of the upper most weaker part of the mantle. As we move from the lithosphere to the asthenosphere the temperature increases.

What is the Earth's 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.

What best describes the 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.Nov 23, 2021

What is the lithosphere and the asthenosphere and how are they similar?

The lithosphere is rigid and is made of the crust and the upper part of the mantle. The asthenosphere is plastic and is made of the softer part of the mantle. The lithosphere is plastic and is made of continental crust. The asthenosphere is rigid and is made of oceanic crust.Dec 3, 2021

What is the role of the lithosphere and asthenosphere in plate tectonics?

The asthenosphere, under the lithosphere, is so hot is enables the plates to move because the material under can flow. The interactions between the lithosphere and the asthenosphere help to explain plate tectonics. This is the cold and rigid outermost rock layer. A plate boundary exists where the tectonic plates meet.Dec 12, 2021

How do the lithosphere and asthenosphere differ 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.

Which best describes 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.May 20, 2015

What statement best describes the lithosphere?

The correct answer is Crust and Upper mantle. It is the outer solid part of the earth, including the crust and uppermost mantle.

Which is the best description of the characteristics of the asthenosphere?

What is the best description of the characteristics of the asthenosphere? The asthenosphere is solid upper mantle material that is so hot that it behaves plastically and can flow. The lithosphere rides on the asthenosphere.Jan 2, 2022

What is the relationship between lithosphere and asthenosphere?

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.Nov 24, 2021

How does the lithosphere and asthenosphere differ from each other?

The primary difference between the lithosphere and the asthenosphere is that the rocks of the asthenosphere are more ductile than those in the lithosphere, which means that they can flow like silly putty, whereas the rocks in the lithosphere just bend or break. That is why the lithosphere is made up of tectonic plates.Jan 21, 2013

What is the lithosphere made of?

The lithosphere is composed of both the crust and the portion of the upper mantle that behaves as a brittle, rigid solid. The lithosphere is the outermost mechanical layer, which behaves as a brittle, rigid solid. The lithosphere is about 100 kilometers thick.

How thick is the lithosphere?

The lithosphere is about 100 kilometers thick. How are crust and lithosphere different from each other? The definition of the lithosphere is based on how Earth materials behave, so it includes the crust and the uppermost mantle, which are both brittle.
