The pressure in the stiffer mantle, which is part of the Earth's upper mantle, increases with depth due to the weight of the overlying rock. At depths of about 400 to 700 kilometers, pressures can reach approximately 10 to 20 gigapascals (GPa). This high pressure contributes to the mantle's rigidity and the behavior of materials under these conditions, influencing geological processes like plate tectonics and mantle convection.

The stiffer mantle, often referred to as the upper mantle, is primarily composed of silicate minerals rich in magnesium and iron, such as olivine, pyroxene, and garnet. These minerals are denser and more viscous compared to those found in the lower mantle, contributing to the upper mantle's rigidity. The high pressure and temperature conditions at these depths also influence the physical properties, making the mantle stiffer and more resistant to flow.
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

Stiffer mantle.
Its about .1 to 1.5 million atmosheres.
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.
Its about .1 to 1.5 million atmosheres.
Another name for the stiffer mantle is the lithosphere.
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.

High temperature and high pressure are inferred to occur within Earth's stiffer mantle. As depth increases in the mantle, both temperature and pressure increase. This combination of high temperature and pressure allows for the solid rock to exhibit ductile behavior, resulting in the flow of solid material over long periods of time.
