How is the temperature and pressure in the Earth's mantle related to the depth of the mantle?

The degree of temperature and exertion of pressure by the molten materials (magma) within the mantle is directly proportional to its depth. This means that, the deeper you go down the mantle the higher the degree of temperature and pressure exerted.

The driving forces to tectonic plates are related to convection currents in earths what?
mantle.
How many layers in earths mantle?
there are 7 layers in earths mantle.
Which combination of temperature and pressure is inferred to occur within earth's stiffer mantle?
thez nuts
Where is most of the earths new crust found?
in the earths mantle
What are facts about earths upper mantle?
Temperature is about 2000 to 3000 degrees celsius maybe less.The mantle is hot but not the hottest layer.It is is the second layer of the Earth. The mantle is the thickest layer of the earth, it is the layer of the earth beneath the crust.Upper mantle and Lower mantle are the two parts of the mantle, The lower mantle is deeper and denser than the upper mantle .
Why isn't the earths entire mantle liquid?
"Because there are different pressure-temperature slopes for adiabatically ascending bodies and melting curves."
When rocks return to earths mantle to earths mantle they can eventually melt and become magma. and are the main factors that control this change.?
heat and pressure
Is the earths lower mantle hot?
the average temperature for the Earth's lower mantle is 5400 degrees
Which layer of the Earths atmosphere is the pressure inferred to be 1.0 million atmospheres?
Stiffer mantle.
The driving forces to tectonic plates are related to convection currents in earths what?
mantle.
What in earths mantle causes tectonic plates to move?
Convection currents in the mantle are what causes tectonic plates to move. Uneven heating of the mantle results from radioactive decay of some long-lived isotopes in the mantle, which are not evenly distributed.
Why are mantle rocks solid even though the Earth's interior temperature is very hot?
The melting temperature of materials is dependent on the pressure that is applied, whereby the higher the pressure, the higher the melting temperature. As such the rocks in the mantle are experiencing such a high pressure, that their melting point is driven up beyond the temperature within the Earth's mantle so they remain solid.
Which temperature is inferred to exist within Earths plastic mantle?
2000 celcius
Why do few earthquake happen in earths mantle?
Few earthquakes happen in the earths mantle do to the fact that the mantle has a folded deformation. This means that the amount of pressure on the mantle caused it to deform.
How many layers in earths mantle?
there are 7 layers in earths mantle.
How does pressure determine whether the mantle is solid or liquid?
The melting temperature of materials is affected by their confining pressure. The higher the pressure the higher the melting temperature. As such as you move deeper into the mantle, the tempraeture will increase, but because of the overlying material so to will the confining pressure which drives up the melting temperature. When high temperature mantle material moves nearer to the surface such as near a mid-ocean-ridge the confining pressure falls faster than the materials temperature and this can cause the melting point to drop below the temperature of the material leading to melting.
What are the main differences between the layers of mantle?
Mineralogy, pressure, temperature, and density differences exist among the 'layers' of the mantle.
