To turn carbon into diamonds, it takes between 237,000 times atmospheric pressure (24 gigapascals) to 1.3 million times atmospheric pressure (136 gigapascals). High pressure and high temperatures in the earth's lower mantle crust are pertinent for the creation of diamonds. However, diamonds are made from carbon; not coal.Know More
Diamonds are formed when carbon is under an immense amount of pressure and heat. The carbon atoms found in coal are squeezed and heated, and then pushed toward the earth's surface, where they cool and become diamonds.
Plants are the source material for coal, and most diamonds are much older than the earth's first land plants. This means the earth's diamond deposits were created long before the existence of coal.Learn more about Geology
Colored diamonds form under the same conditions as clear diamonds, but their colorations are due to chemical impurities or structural imperfections within the crystal lattice. Although all diamond color varieties are possible in nature, some are easier to replicate within a laboratory setting than others.Full Answer >
It takes approximately 7 pounds of pressure to break a human clavicle, or collarbone. The clavicle is made up of a single, long, thin bone, one of two that extends from the shoulder blades to the breastbone. Commonly, the clavicle is broken by falling on the shoulder.Full Answer >
The basic difference between coal and coke is that coal is the natural source and coke is the derivative product produced by destructive distillation. Both are used as fuel, but coke contains a higher carbon content and few impurities. Coke is also used during iron ore smelting as a reducing agent.Full Answer >
The first recorded discovery of coal in the United States is believed to be on the Illinois River in 1679 by French explorers. Historians, though, believe that the Chinese discovered coal more than 3,000 years ago.Full Answer >
