These plates usually float smoothly along the mantle but at times they build up pressure What happens when the pressure snaps the rock?

Why can diamonds form in the mantle?
The weight of the rocks above the mantle results in high pressure.Diamonds need high temperatures and pressure to form from carbon. Diamonds form in the mantle in certain zones where conditions are right for them to do so.There just happens to be the right critical temperature-pressure-mineral environment in the mantle in certain zones for their formation.
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
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

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
Are all earthquakes in the earth's crust?
It happens in the mantle and crust because the focus is the starting point and it is usually starts at the lithosphere(mantle) or near the mantle, but almost there.The focus rises up and the epicenter is the start of the earthquake.
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 happens to the mantle rock as you go deeper into the mantle?
earthquakes and volcanoes
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 happens to plates on the mantle?
Plates on the Earth's mantle are carried around by convection currents from the magma. This happens incredibly slowly.
