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 >
Coal is a cost-effective and reliable form of energy, but there are concerns about the impact that coal has on the environment. It is a fossil fuel that is found in mines in countries around the world, including the United States.Full Answer >
The most common type of coal is anthracite, which has a hardness of 2.2 when compared to the Moh's scale of mineral hardness, according to the Ted Pella website. However, since coal is not a mineral, it is not officially measured in this way.Full Answer >
