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 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 word best describes the hot weak inner part of the upper mantle which can flow?
asthenosphere
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?
There is no layer of the Earth that is made of Magma (molten rock). There is a layer called the Mohorovicic Discontinuity (or Moho) which is the boundary between the Earth's lower crust and upper mantle. The asthenosphere is a mechanically weak ductily-deforming region of the upper mantle which lies below the Moho. The asthenosphere is thought to be the source of some magma but it is not a complete layer of molten rock.

What statement describes the asthenosphere?
Soft layer of the Mantle in which tectonic plates move.

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
