Matter in the Asthenosphere is in the molten or semi-molten state. This is because its temperatures can peak at 3,000 degrees Celsius. Its composition consists of magnesium and iron silicates. The Asthenosphere plays a key role in the movement of tectonic plates.

What layer of earth is made of melted rock and solid?
the inner core
What is ''plastic'' rock and how does it move?
The asthenosphere, moves with convection
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 is the behavior of the crustal plates in relation to the asthenosphere?
Crustal (or lithospheric) plates are pulled or pushed by the movement of heated rock in the asthenosphere.
Great pressure in the asthenosphere keeps the rock there mostly?
solid
Is Asthenosphere a liquid rock?
No. The rock of the asthenosphere forms a ductile solid.
Why does rock in the asthenosphere behave differently from the rock above?
The rock in the asthenosphere behaves differently from the rock above because the rate of deformation is different.
Does lithosphere or asthenosphere contain partly melted rock from the upper part of the mantle?
The Asthenosphere.
Why does most of the rock in the asthenosphere remain solid?
The rock in the asthenosphere is under immense pressure from the overlying rock. Increased pressure raises the melting point of most substances.
What layer of earth is made of melted rock and solid?
the inner core
What type of layer is the Asthenosphere?
The Asthenosphere is a layer of the upper mantle.
What is the similarIty between the asthenosphere and the lithosphere?
They are chemically the basic same type of rock. Heat and pressure cause the rock to become more fluid as depth increases, so the solid rock (termed lithosphere) floats upon the more liquid rock of the asthenosphere.
Soft layer of rock in the mantle?
asthenosphere
What does the asthenosphere contain?
The asthenosphere contains ultramafic rock that is ductile due to the extreme heat and pressure it experiences.
What is a layer of slowly forming rock in the mantle?
Asthenosphere
Is the asthenosphere brittle rock?
yes it is brittle but shifting
The layer of rock that has convection currents flowing?
The asthenosphere.
