What is the relationship between the 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.
What are the relationships among the mantle the crust the asthenosphere and the lithosphere?
The lithosphere contains the crust and the uppermost layer of solid mantle. The asthenosphere contains the liquid layer of the upper mantle.
Which of these describes the lithosphere and asthenosphere?
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 relationship between the lithosphere and asthenosphere abeka?
What is the relationship between the lithosphere and asthenosphere? The rigid plates of the lithosphere float on the plastic rock of the asthenosphere. Currents in the asthenosphere move the plates.
Where is the lithosphere relative to the asthenosphere?
The lithosphere is the solid, outer part of the Earth. 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.
What is the relationship of the mantle to the lithosphere asthenosphere and mesosphere?
The mantle extends to the core-mantle interface at approximately 2900 km depth. Thus, the mantle contains the lower portion of the lithosphere, the asthenosphere, and the mesosphere. The crust is made of the upper portion of the lithosphere.
What is the relationship between lithosphere asthenosphere and mesosphere?
The mesosphere refers to the mantle in the region under the lithosphere and the asthenosphere, but above the outer core. The upper boundary is defined as the sharp increase in seismic wave velocities and density at a depth of 660 kilometers (410 mi). This layer should not be confused with the atmospheric mesosphere.
What is in the asthenosphere?
The asthenosphere is a part of the upper mantle just below the lithosphere that is involved in plate tectonic movement and isostatic adjustments. It is composed of peridotite, a rock containing mostly the minerals olivine and pyroxene.
What is in the lithosphere?
The lithosphere is the solid, outer part of the Earth. 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.
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.
What are 3 ways the asthenosphere is different from the lithosphere?
The Lithosphere is composed of the crust and upper most solid mantle….Comparison of the Lithosphere and Asthenosphere.
| Lithosphere | Asthenosphere |
|---|---|
| Has a lower density than the asthenosphere | Asthenosphere is denser than the lithosphere |
| Allows for conductive heat transfer | Allows for advective heat transfer |
Does the lithosphere and asthenosphere interact?
The asthenosphere is solid upper mantle material that is so hot that it behaves plastically and can flow. The lithosphere rides on the asthenosphere.
Is the lithosphere part of the asthenosphere?
Summary. 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.
How are the asthenosphere and the lithosphere different?
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.
Is asthenosphere part of lithosphere?
The lithosphere is the solid, outer part of the Earth. 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.
How did the lithosphere and asthenosphere differ?
While lithosphere is hard and rigid, Asthenosphere is a layer made up of molten rocks. Rocks are under severe pressure in Asthenosphere, whereas they face much less pressure in lithosphere.
What is the role of the lithosphere and asthenosphere in plate tectonics?
In plate tectonics, Earth's outermost layer, or lithosphere—made up of the crust and upper mantle—is broken into large rocky plates. These plates lie on top of a partially molten layer of rock called the asthenosphere.
What is the difference between 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.
How does the asthenosphere affect the lithosphere?
Convection currents generated within the asthenosphere push magma upward through volcanic vents and spreading centres to create new crust. Convection currents also stress the lithosphere above, and the cracking that often results manifests as earthquakes.
How do the lithosphere and asthenosphere differ from each other 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.
How does asthenosphere become lithosphere?
The lithosphere-asthenosphere boundary, or LAB, represents the transition from hot, convecting mantle asthenosphere to overlying cold and rigid lithosphere. The oceanic lithosphere thickens as it cools over time, and eventually sinks back into the mantle at Earth's so-called subduction zones.
