The asthenosphere is part of the mantle, so the question is misguided. It is less dense than the lower mantle.

Is the lower mantle rock stronger than the asthenosphere?

Yes, the lower mantle rock is typically stronger than the asthenosphere. The lower mantle exhibits solid-like behavior due to high pressure, while the asthenosphere is partially molten and represents a weaker layer of the Earth's mantle.


What is the definition of the word asthenosphere?

The asthenosphere is the highly viscous, mechanically weak and ductilely -deforming region of the upper mantle of the Earth.


Is the mantle part of the asthenosphere?

Yes, the aesthenosphere is the part of the upper mantle that is highly viscous and mechanically weak behaving as a ductile solid.


What is another word for asthenosphere-?

Other words that can be used for asthenosphere are crust and mantel.


What is asthenosphere?

The asthenosphere is the viscous region of the upper mantle of the Earth that lies just below the lithosphere.


What is the plastic zone below the upper mantle?

The plastic zone below the upper mantle is called the asthenosphere. It is a semi-fluid layer of the upper mantle where rock can flow like a viscous fluid over long periods of time. The asthenosphere plays a crucial role in the movement of tectonic plates.


What layer lies beneath the lithosphere?

The asthenosphere.


Is asthenosphere the lower mantle?

No. The asthenosphere is part of the upper mantle.


What is the relationship between the mantle and the asthenosphere?

The asthenosphere is a layer within the upper mantle. It is a more ductile and partially molten region of the mantle that allows for the movement of tectonic plates above it. The mantle, which includes the asthenosphere, is the layer of the Earth located between the crust and the core.


What do earths tectonic plates do?

The plates (continental and ocean plates) ride atop the asthenosphere, a layer of viscous rock in the upper mantle beneath the crust.


Is the asthenosphere the mantle?

The asthenosphere is part of the mantle, one of several layers.


What statement describes the asthenosphere?

Soft layer of the Mantle in which tectonic plates move.
