What else can I help you with?
What portion of the mantle is hot enough to begin melting rocks into magma?
asthenosphere
How are the asthenosphere and lithosphere involed with plate tectonics?
The lithosphere is the brittle surface layer composed of the crust and uppermost mantle. The asthenosphere is the ductile upper mantle on which the lithosphere is able to move.
What is the soft layer of the mantle where tectonic plates move?
asthenosphere
Which layer of earth lies below the crust?
The asthenosphere and the mantle.
What do geologists call the crust and the upper most mantle?
Lithosphere
What do geologists believe heats thee upper mantle portion of the asthenosphere?
Geologists believe that the upper mantle portion of the asthenosphere is primarily heated by the residual heat left over from the formation of the Earth, known as radiogenic heat. This heat is generated by the decay of radioactive isotopes present in the mantle. Other sources of heat include the heat transferred from the core and the heat produced by ongoing mantle convection.
What is the portion of the mantle?
The asthenosphere
What part of the mantle is made of soft rock that bends like plastic.?
A portion of the upper mantle known as the asthenosphere.
What contains the lower mantle?
The mantle extends to the core-mantle interface at approximately 2900 km depth. Thus, the mantle contains the lower portion of the lithosphere, the asthenosphere, and the mesosphere. The crust is made of the upper portion of the lithosphere.
What is the Aesthnosphere?
The asthenosphere is a portion of the upper mantle of the Earth, just below the lithosphere. http://en.wikipedia.org/wiki/Asthenosphere
What portion of the mantle is hot enough to begin melting rocks into magma?
asthenosphere
Is the upper mantle part of the lithosphere or asthenosphere?
The The crust and the uppermost layer of the mantle form the lithosphere. The asthenosphere, which is still in the upper mantle, is the next layer down.
What is the plastic portion of the upper mantle?
The plastic portion of the upper mantle is known as the asthenosphere. This region consists of partially molten rock that allows the lithospheric plates to move and interact. The asthenosphere plays a crucial role in plate tectonics and the movement of Earth's tectonic plates.
Is asthenosphere the lower mantle?
No. The asthenosphere is part of the upper mantle.
Is the lower portion of the crust and the upper portion of the mantle called the core?
No, the lower portion of the crust and the upper portion of the mantle together are not called the core. The core is a separate layer found beneath the mantle, and it is divided into the outer core and inner core based on composition and properties.
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 range of temperature that exist within the asthenosphere?
The asthenosphere is the lower portion of the Earth's mantle. Its temperature ranges from 1000 degrees Celsius to 2500 degrees Celsius.
