the pressure builds up from tectonic plates moving past each other causing gaps and then volcanoes are produced. hope it helps.

How are pressure and heat involved in melting rock in the mantle?
It is involved in the Mantle because heat Is used for the temepeter and pressure is for how close the mantle is
What is the pressure of the upper mantle?
somewhere between 1000 to 4000 degrees Celsius.
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.
How does the weight of the lithosphere affect the mantle?
The rock of the mantle is hot enough that it would melt at surface pressure. The weight of the lithosphere creates such great pressure on the mantle that it remains solid.
Does the mantle have the most pressure?
yes it does
What causes pressure to cause diamonds in the mantle?
The weight of the rocks in the crust and upper mantle results in the pressure that allows diamonds to form.
Why is the lower mantle denser the the upper mantle?
The lower mantle is under greater pressure than the upper mantle, compressing the rock into a denser form.
What pressure allows diamonds to form in the mantle?
Overburden or lithostatic pressure.
What is the least rigid part of the mantle?
The upper mantle is less rigid because the pressure is lower
What causes the pressure to allow diamonds to form in the mantle?
The weight of the rocks in the crust and upper mantle.
How much pressure does the crust mantle and core have?
it has 7,201 km of pressure for each
What is the Solid layer of earth that can flow because of great heat and pressure?
The mantle is the solid layer of earth that can flow because of great heat and pressure
