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.
Gravity and the mass of rock above the diamond stability zone.
Winds are deflected to the right in the Northern Hemisphere because of the earths rotation.
It causes the air to remain by the planet Earth in the first place. Also, it causes the air pressure; about 100,000 Pascal (Newton per square meter) at sea level.
earths rotation
Mama rises when it is less dense than the rock surrounding it, and when the area around it allows free movement. The pressure allows the magma to convert form a liquid to a gas, which causes it to rise.
The weight of the rocks in the crust and upper mantle results in the pressure that allows diamonds to form.
The weight of the rocks in the crust and upper mantle results in the pressure that allows diamonds to form.
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.
Gravity and the mass of rock above the diamond stability zone.
Pressure and extreme heat.
Weight causes density, density causes pressure, pressure causes heat. Heat and pressure change rocks into other rocks, which are metamophic.
The weight of the rocks in the crust and upper mantle.
Extreme heat and pressure deep in the earth forms diamonds all over the earth, except on the continents of Europe and Antarctica.
Pressure from the earths core
Atmospheric pressure is caused by the force of the air above the earths surface. It is measured by the point in which the air meets the atmosphere.
Because the density of the force increases.
People can't efficiently make diamonds, it takes thousands of pounds of pressure and extreme heat.This process happens naturally underground. Carbon is compressed by the amount of mass on top of it and heated by the core. The pressure from the crust is what causes diamonds to be so dense/hard.Another AnswerThere are man-made diamonds, made from carbon under enormous pressure and extreme high heat.
