The stiffer mantle, often referred to as the upper mantle, extends from about 35 kilometers (22 miles) to approximately 660 kilometers (410 miles) below Earth's surface. It is composed of solid rock that behaves viscously over long periods, accommodating tectonic processes without flowing like the molten rock found in the lower mantle. The transition between the upper and lower mantle occurs at around 660 kilometers, where the material becomes more ductile due to increased pressure and temperature.
What else can I help you with?
What is the range of density within the mantle?
The stiffer mantle (upper) is one of the layers of the earth's crust and composed of hot liquid rock. The range of density is between 3-100 or 3.4g/cm and 4.3g/cm.
What is the The inferred temperature at the interface between the stiffer mantle and the asthenosphere is closet to?
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.
What is the depth pressure and temperature where the plastic mantle meets the stiffer mantle?
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.
What is the inferred temperature at the interface between the stiffer mantle and the asthenosphere closest to?
The inferred temperature at the interface between the stiffer mantle and the asthenosphere is typically estimated to be around 1300 to 1500 degrees Celsius. This temperature range corresponds to the conditions under which the upper mantle rocks begin to behave in a ductile manner, allowing for the movement of the asthenosphere. The exact temperature can vary based on local geological conditions and the composition of the mantle materials.
Which temperature is inferred to exist in Earths plastic mantle?
The temperature in Earth's plastic mantle, specifically in the asthenosphere, is generally inferred to range from about 1,300°C to 3,000°C (2,372°F to 5,432°F). This temperature range allows the mantle rocks to behave in a ductile manner, enabling them to flow slowly over geological timescales. The heat is generated from both the residual heat from Earth's formation and the decay of radioactive isotopes within the mantle.
What is the range temperature within the stiffer mantle?
The temperature range within the stiffer mantle is between 500 and 900 degrees Celsius. This region is known as the upper mantle and is composed of solid rock that can deform under high pressure and temperature.
What is the range of pressure of the stiffer mantle?
Its about .1 to 1.5 million atmosheres.

What is the range of pressure within the stiffer mantle?
The pressure within the stiffer mantle ranges from about 14 GPa (gigapascals) at the upper boundary to over 136 GPa at the core-mantle boundary. This high pressure contributes to the solid-state behavior of the mantle material despite its high temperature.

What is the stiffer mantle?
The density of Earth's mantle varies depending on its depth. The part right below the crust has a density of about 3.4 grams per cubic centimeter while the lowest part of the mantle is 5.6 grams per cubic centimeter.

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