Want this question answered?
Because towards the center of the earth, there is more mass on top of it, so there is more pressure. All of the other layers, and the stuff on top of the earth is pushing down on it from all sides. For the mantle, its only the stuff on the top of the earth that is putting pressure on it.
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.
Diamonds are believed to be formed about 90 miles below the surface of the Earth, in the mantle. So, the weight of the Earth above them creates the pressure to form diamonds.
thez nuts
Thermosphere or the ionosphere is the thickest layer on earth. It reaches a height 400 kilometers.
it will steady as liquid form and hot
in both the Earth's lithosphere and the Earth's mantle.
The mantle is the solid layer of earth that can flow because of great heat and pressure

something about pressure i guess lol :)

The earth's mantle would have formed initially in the same way as the crust, by the cooling of the earth but as for the metamorphic rock that defines the earth's mantle, that would have taken millions of years of extreme heat and pressure for it to form.

The overburden load / self weight of the approximately 150 to 190 km of material that overlies the layer of the Earth's mantle where diamonds form creates the pressure required.
Stiffer mantle.
