Why is the asthenosphere weaker than the lithosphere?
In the lithosphere, the rocks are cooler, stronger, and more rigid than the asthenosphere. It is rock strength that differentiates the lithosphere from the asthenosphere. The differences in strength between rock in the lithosphere and rock in the asthenosphere is a function of temperature and pressure.
What are the similarities between the lithosphere and asthenosphere?
What are the similarities between the lithosphere and the 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.
What are 5 facts about lithosphere?
✦ Following are the major plates of the lithosphere:
- African Plate
- Antarctic Plate
- Eurasian Plate
- Indo-Australian Plate
- North American Plate
- Pacific Plate
- South-American Plate.
Is the asthenosphere is hotter than the lithosphere?
asthenosphere, zone of Earth’s mantle lying beneath the lithosphere and believed to be much hotter and more fluid than the lithosphere. The asthenosphere extends from about 100 km (60 miles) to about 700 km (450 miles) below Earth’s surface. Heat from deep within Earth is thought to keep the
Why is the lithosphere rigid while the asthenosphere is not quizlet?
Lithosphere consists of the crust and the upper mantle, and behaves like a hard layer that breaks and bends. is warm enough to flow slowly. Why is the lithosphere rigid while the asthenosphere is not? The temperature in the asthenosphere is higher than the lithosphere so the rock is softer.
Is the asthenosphere more rigid than the lithosphere?
We can tell the difference between the lithosphere and asthenosphere because they behave differently. The lithosphere is more rigid, and the asthenosphere is more elastic and molten.
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 lithosphere rigid?
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.
How does the lithosphere differ from 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.
Is the asthenosphere rigid?
asthenosphere. The asthenosphere is the semi-rigid part of the middle mantle that flows like hot asphalt under a heavy weight. The crust and the upper layer of the mantle together make up a zone of rigid, brittle rock called the Lithosphere.
How are the lithosphere and the asthenosphere similar quizlet?
The lithosphere and the asthenosphere are both parts of a mantle and parts of the interior earth. The lithosphere is the hard and rigid uppermost part of the mantle and crust. The asthenosphere is the soft layer in the lower part of the mantle.
How does the lithosphere and asthenosphere interact?
The lithosphere is broken into giant plates that fit around the globe like puzzle pieces. These puzzle pieces move a little bit each year as they slide on top of a somewhat fluid part of the mantle called the asthenosphere. All this moving rock can cause earthquakes.
What are the relationships among the mantle the crust the asthenosphere and the 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.
Why is lithosphere rigid?
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.
Why is the lithosphere solid?
The lithosphere is the solid, outer part of the Earth. It is made up of the brittle crust and the top part of the upper mantle. It is a rigid, rocky outer layer of the Earth, consisting of the crust and the solid outermost layer of the upper mantle.
Is the asthenosphere brittle?
The only difference is that the asthenosphere is not as brittle (not as solid) as the lithosphere, mostly because the asthenosphere is hotter. (It is hotter because it is deeper in the earth.)
