What is the weak upper portion of the mantle which behaves plastically?
The weak upper portion of the mantle that behaves plastically is called the asthenosphere. It is located beneath the lithosphere and is responsible for the movement of tectonic plates due to its ability to flow slowly over geological time scales. The asthenosphere plays a key role in the process of plate tectonics.
What is the soft weak upper portion of the mantle where the lithospheric float and move around?
The soft, weak upper portion of the mantle is known as the asthenosphere. It lies beneath the lithosphere and is composed of partially molten rock that allows the rigid lithospheric plates to float and move over it. This movement is a key driver of plate tectonics, leading to geological phenomena such as earthquakes and volcanic activity.
Is the lithosphere a solid that floats on the inner part of the mantle?
Yes, the lithosphere is the rigid outer layer of the Earth that consists of the crust and the upper part of the mantle. It is broken into tectonic plates that float on the semi-fluid asthenosphere below.
What is the hot weak part in the upper mantle?
The hot, weak part of the upper mantle is known as the asthenosphere. This region lies beneath the lithosphere and is characterized by partially molten rock that allows for slow, convective movement. The increased temperature and pressure in the asthenosphere reduce its viscosity, enabling the tectonic plates of the lithosphere to move over it. This dynamic behavior plays a crucial role in plate tectonics and geological processes.
Partially molten, plastic-like, flowing layer located below the solid part of Earths mantle?
Partially molten, plastic like, flowing layer located below the solid part of Earth's mantle is the Asthenosphere. The asthenosphere is mechanically weak and ductiley deforming region of the upper mantle.
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 word best describes the hot weak inner part of the upper mantle which can flow?
asthenosphere
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.
What does asthenoshere mean?
the answer is the solid , but plastic layer found in the upper mantle ................hope this helps bye bye .

Which layer of the earth does the magma form?
Magma forms in the mantle layer of the Earth. It is a molten rock material that originates from the partial melting of rocks in the upper mantle. Magma can rise to the Earth's surface through volcanic eruptions.
What statement describes the asthenosphere?
Soft layer of the Mantle in which tectonic plates move.
Is the lithosphere a solid that floats on the inner part of the mantle?
Yes, the lithosphere is the rigid outer layer of the Earth that consists of the crust and the upper part of the mantle. It is broken into tectonic plates that float on the semi-fluid asthenosphere below.
Partially molten, plastic-like, flowing layer located below the solid part of Earths mantle?
Partially molten, plastic like, flowing layer located below the solid part of Earth's mantle is the Asthenosphere. The asthenosphere is mechanically weak and ductiley deforming region of the upper mantle.
How does hot spot form?
A hot spot is formed on a point of the earths surface where strong upward convection currents or plumes of hot magma in the upper mantle push up below the plates of the lithosphere causing volcanic activity. no it doesn'twhen the mantle is weak
How is the lithosphere different then the adthosphere?
The lithosphere is defined as the crust plus the brittle, uppermost mantle to which it is attached. The part of the upper mantle called the asthenosphere is ductile, and is the portion of the mantle on which the lithosphere 'floats'. Essentially, it is a difference in the degree of ductility. The lithosphere is brittle; the mantle is ductile.
Where is the asthenosphere located on earth?
The Earth's asthenosphere starts at depths of around 100 to 200 km below the surface and extends down to around 700 km. This is part of the upper mantle.Directly below the lithosphere. The asthenosphere is located between 100-350 km below the surface of the Earth. The Asthenosphere is a ductile yet solid layer located inthe upper mantle.in the upper mantle
