Examples of asthenosphere
asthenosphere
Instead, Keppler has been investigating water solubility in the asthenosphere.
From the sciencedaily.com
The outer layers of the Earth are divided into lithosphere and asthenosphere.
From the en.wikipedia.org
It also fails to explain why there is a lower boundary to the asthenosphere.
From the sciencedaily.com
It was found that the asthenosphere had invaded the overlying lithosphere.
From the en.wikipedia.org
The lithosphere is only 30 km and there is a low seismic velocity asthenosphere below.
From the en.wikipedia.org
Scientists think that the secret lies beneath the crust, in the slippery asthenosphere.
From the sciencedaily.com
Below the lithosphere lies the asthenosphere, which is a more viscous zone of the mantle.
From the en.wikipedia.org
These sections float on a gooey layer of partly molten rock known as the asthenosphere.
From the time.com
The asthenosphere is of indeterminate thickness and behaves plastically.

- The lower layer of the crust
- The asthenosphere (from Greek u1F00u03C3u03B8u03B5u03BDu03AEu03C2 asthenu1E17s 'weak' + "sphere") is the highly viscous, mechanically weak and ductilely deforming region of the upper mantle of the Earth. It lies below the lithosphere, at depths between approximately 80 and 200u00A0km (50 and 120u00A0miles) below the surface. The Lithosphere-Asthenosphere boundary is usually referred to as LAB...
- The zone of the Earth's upper mantle, below the lithosphere
- The shell within the earth, some tens of kilometers below the surface and of undefined thickness, which is a shell of weakness where plastic movements take place to permit pressure adjustments.
- A plasitc or partially molten layer of the Earth's upper mantle on which the continents "float." Variable in thickness, with its upper boundary at depths of 10 km or more and its lower boundary at depths as great as 800 km.*
- Part of the Earth's mantle that lies below the lithosphere, at depths between about 100 and 350 kilometers. Rock here is relatively soft because its high temperature and relatively low confining pressure enable a small amount of melt to form and lubricate its movement.
- The uppermost layer of the mantle, located below the lithosphere. This zone of soft, easily deformed rock exists at depths of 100 kilometres to as deep as 700 kilometres.
- A weak spherical shell below the lithosphere.
- The asthenosphere is a division in the mantle situated below the lithosphere. This zone of weak material exists below a depth of about 62 miles (100 km) and in some regions extends as deep as 435 miles (700 km). The rock within this zone is easily deformed. Source: Lutgens and Tarbuck (1992)
