Hot, softer upper mantle
The asthenosphere is part of the upper mantle, which lies beneath the Earth's lithosphere. It is a semi-fluid layer of the mantle that allows the lithospheric plates to move and float on top of it.
The asthenosphere is not a type of rock, but rather a layer in the Earth's mantle. It consists of partially melted rock that behaves as a plastic-like material, allowing tectonic plates to move on top of it.
The Earth has three main layers: the core (inner and outer core), the mantle, and the crust. The core is composed mostly of iron and nickel, the mantle is made up of solid rock that can flow over long periods of time, and the crust is the outermost layer where we live, made up of solid rock that floats on the semi-fluid mantle.
The solid crust floats on the asthenosphere because it is less dense than the underlying semi-solid asthenosphere. This buoyancy is due to the difference in densities between the materials, with the less dense crust able to "float" on the more dense asthenosphere.
The temperature of the asthenosphere ranges from about 1300 to 2400 degrees Fahrenheit (700 to 1300 degrees Celsius). This layer of the Earth's mantle is partially molten, allowing it to flow and contribute to plate tectonics. The actual temperature can vary depending on the depth within the asthenosphere.
Athenosphere is an extremely viscous liquid.
solid
liquid
The lithosphere in thinner!!!!! duuaaa...lol it is thinner because it is between the crust and the outer core and the athenosphere is every where!!!!!!!!!!!!!!!1
In the uppermantle below the lithosphere.
crust
The correct spelling is asthenosphere.
The athenosphere
20000 miles thick
the ductile athenosphere.
the ductile athenosphere.
yes it is
