The asthenosphere is a semi-fluid layer of the Earth's mantle located beneath the lithosphere, extending from about 100 to 700 kilometers below the surface. It plays a crucial role in plate tectonics, as it allows the rigid lithospheric plates to move over it due to its ductility and partial melting. The asthenosphere is characterized by increased temperature and pressure, which contribute to its plasticity. This layer is essential for the convection currents that drive the movement of tectonic plates.
It is called the asthenosphere.

The asthenosphere is part of the mantle, one of several layers.
Yes. That is what the asthenosphere is.
The lithosphere sits on top of the asthenosphere.
true.
No. The asthenosphere is thought to contain only around 5% melt.
Because of something called Isostacy-the gravitational equilibrium between lithosphere and asthenosphere, such that plates "float" at an elevation that dependes on the thickness and density. EX. Think floating ice cubes
It is called the asthenosphere.

The asthenosphere is about 1600 degrees Celsius. :)

No. The asthenosphere is plastic in texture.
