Diamonds are formed deep within the Earth about 100 miles or so below the surface in the upper mantle. Obviously in that part of the Earth it's very hot. There's a lot of pressure, the weight of ...

Natural diamonds are forged in the Earth’s upper mantle, where temperatures soar at 900–1400°C and pressures reach 5–6 gigapascals—thousands of times greater than the pressure at sea level.

But landforms can also be created when the lithosphere, which consists of the crust and the relatively brittle upper layer of the mantle, gets especially thick. Mountains create a lot of pressure ...
