Temperature is relatively uniform throughout the asthenosphere due to its semi-molten state. This consistent temperature allows for the flow of material within the asthenosphere, contributing to the movement of tectonic plates.
The inferred temperature at the interface between the stiffer mantle and the asthenosphere is closest to approximately 1300 to 1500 degrees Celsius (2372 to 2732 degrees Fahrenheit). This temperature range is crucial for the behavior of the asthenosphere, as it becomes partially molten and more ductile, allowing for mantle convection and tectonic plate movement.
The asthenosphere has a density that is slightly less than the overlying lithosphere. It is composed of hot, semi-fluid rock that allows the lithosphere to move and deform over it due to its lower density and viscosity. The exact density can vary depending on temperature, pressure, and composition of the material.
It is called the asthenosphere.

The asthenosphere lies just below the lithosphere and composes the upper part of the Earth's mantle. Its temperature is 1300 degrees Celsius.
The asthenosphere is the lower portion of the Earth's mantle. Its temperature ranges from 1000 degrees Celsius to 2500 degrees Celsius.

The asthenosphere lies beneath the lithosphere, which is where the tectonic plates lie. Because of the high temperature, the asthenosphere has the property to flow (plasticity); the tectonic plates "float" on this flow.
The asthenosphere has plasticity due to the high temperature and pressure conditions present in this region of the Earth's mantle. These conditions allow the rock in the asthenosphere to deform and flow slowly over long periods of time, giving it its plastic behavior.
