The temperature of the plastic mantle, or asthenosphere, is inferred to be about 1600 degrees Celsius.
2000 celcius
Inner Mantle: The average temperature is about 3000ºC Outer Mantle: The average temperature is about 2200ºC
The mantle is typically divided into the upper mantle (including the lithosphere and asthenosphere) and the lower mantle. The upper mantle is rigid and brittle, while the lower mantle is more plastic and capable of flow. The upper mantle plays a crucial role in plate tectonics, whereas the lower mantle's convection currents are thought to drive the movement of tectonic plates.
the plasic like rock of the lower mantle is the asthenosphere
When describing the upper mantle, the term "plastic" refers to the ability of the mantle material to deform and flow over long periods of time under high temperatures and pressures. This plastic behavior allows the mantle to flow and convect, driving plate tectonics and other geological processes.

The plastic zone is also called the asthenosphere,because in the solid bottom part of the mantle, the temperature is sufficient to make the rock plastic, meaning, it flows.
Inner Mantle: The average temperature is about 3000ºC Outer Mantle: The average temperature is about 2200ºC
the upper-mantle rocks are heavier while the lower mantle rocks are semisolid like melted plastic
The mantle is primarily composed of solid rock that is rich in silicate minerals. It is divided into the upper mantle and the lower mantle, with the upper mantle being more rigid and the lower mantle exhibiting more plastic behavior due to higher pressure and temperature. The mantle is responsible for convection currents that drive plate tectonics and is a critical component of Earth's structure.
is the temperature if the stiffer mantle above or below its melting point
Plastic
Inner Mantle: The average temperature is about 3000ºC Outer Mantle: The average temperature is about 2200ºC
The boundary between the plastic (asthenosphere) and the stiffer mantle (lithosphere) is typically found at depths of about 100 to 700 kilometers beneath the Earth's surface. At this depth, the pressure can range from approximately 3 to 25 gigapascals, and temperatures can vary between 1,300 to 3,000 degrees Celsius. This transition zone marks a significant change in the physical properties of the mantle materials.
Yes. The mantle is composed of the plastic mantle, or the upper part, which is partially molten. The stiffer mantle is under it. it is not as molten
Heat transfer by the movement of a heated fluid is called _________?
The crust moves on a plastic like layer of the mantle.
