If you imagine the world as a kettle of boiling water, standing on a lit gas ring. While the steam escapes through the spout, all is well. But if the spout and lid was to become blocked, the steam would create a growing pressure inside the kettle. Eventually, the kettle would burst and the pressure is suddenly released. A bursting kettle is like an erupting volcano, releasing some of the pressure that had built up below the mantle.

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.
Does the mantle lie directly below the inner core?
Yes, the inner mantle is solid rock, due to high pressure.
What causes the lower mantle to remain solid despite high temperatures?
Me because I am so hot
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.
What pressure allows diamonds to form in the mantle?
Overburden or lithostatic pressure.

Does Neptune have a mantle?
YES! Neptune does have a mantle. Neptune's mantle is believed to be enriched with icy water, ammonia and methane. These elements create a high 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

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.
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.
What is the chemical origin of diamond?
Natural diamonds are formed deep within the earth's mantle, under extraordinary high pressure and extreme high heat -- from carbon.
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
