The asthenosphere is the lower portion of the Earth's mantle. Its temperature ranges from 1000 degrees Celsius to 2500 degrees Celsius.

What is the range of the depth in meters of the English channel?
The English Channel is 560km long (max), 240km wide (max) and has a surface area of 75,000 km2
What area of the earth is 200 km down?
asthenosphere
Part of earth's interior that flows like plastic?
Partially molten, plastic like, flowing layer located below the solid part of Earth's mantle is the Asthenosphere. The asthenosphere is mechanically weak and ductiley deforming region of the upper mantle.
The top of the asthenosphere is closest to Earth's surface?
Along a mid-ocean ridge
What rests on the astheosphere?
The Lithosphere Floats on top of the asthenosphere because it is less dense.
What is the range of the asthenosphere?
The temperature range of the asthenosphere is between 1500C-1600C.
How cold is the asthenosphere?
The asthenosphere, which lies beneath the lithosphere in the Earth's mantle, has temperatures that typically range from about 1,300 to 3,000 degrees Celsius (2,372 to 5,432 degrees Fahrenheit). Despite these high temperatures, the asthenosphere is partially molten and behaves like a viscous fluid, allowing tectonic plates to move over it. The exact temperature can vary based on depth and location within the mantle.
How do cyclones affect Asthenosphere?
They don't. Hurricanes are an atmospheric phenomenon. Their effects underground only go as far as recharging groundwater supplies, which don't come anywhere close to the depth of the asthenosphere.
What depth does the asthenosphere start and how far down does it extend?
The asthenosphere begins approximately 100-200 kilometers below the Earth's surface and extends to about 700 kilometers deep. It is a semi-fluid layer of the upper mantle that allows tectonic plates to move and slide.
What is the range of temperature that exist within the asthenosphere?
The asthenosphere is the lower portion of the Earth's mantle. Its temperature ranges from 1000 degrees Celsius to 2500 degrees Celsius.
What keeps Earth's asthenosphere pliable?
The high heat flow from the Earth's interior keeps the asthenosphere pliable by partially melting the rock, which reduces its viscosity. This allows the asthenosphere to flow slowly over geological timescales. Additionally, the high pressure at depth prevents the rock from completely solidifying.
How far below the earth's surface is the asthenosphere?
The asthenosphere begins at around 100-150 km depth in the Earth. This is below the lithosphere, which consists of the crust and the uppermost mantle (the plates in plate tectonics).The asthenosphere is in the mantle, but it is still unclear how much of the mantle (which goes down to a depth of ~2900 km) is actually part of the asthenosphere.
What is the temperature of the earths asthenosphere in degrees celsius?
The asthenosphere lies just below the lithosphere and composes the upper part of the Earth's mantle. Its temperature is 1300 degrees Celsius.
What is another name for the upper mantle 2?
Another name for the upper mantle is the "asthenosphere." This layer lies beneath the Earth's crust and extends to a depth of about 700 kilometers. The asthenosphere is characterized by its semi-fluid properties, allowing for the movement of tectonic plates above it.
Is the lithosphere and asthenosphere boundary above or below the Moho?
The boundary between the asthenosphere and the lithosphere is normally below the Moho (which marks the boundary between the crust and the mantle). The exception to this is below mid-ocean ridges where the moho and the lithosphere / asthenosphere boundary are at the same depth.
How does erosion and wearing away of a mountain affect the depth to which the crust extends into the asthenosphere?
Erosion and wearing away of a mountain decreases the weight of the crust, causing it to rise higher and extend deeper into the asthenosphere. This process is known as isostatic rebound. As material is removed from the surface through erosion, the crust floats higher on the denser asthenosphere below, causing it to sink deeper.
What contains the lower mantle?
The mantle extends to the core-mantle interface at approximately 2900 km depth. Thus, the mantle contains the lower portion of the lithosphere, the asthenosphere, and the mesosphere. The crust is made of the upper portion of the lithosphere.
