Diamond formation occurs naturally in the earth’s crust but it is now possible to produce diamonds artificially in labs from any carbon. What Are Diamonds Age and origin of Diamonds Diamond Formation in The Earth’s Crust Diamond Formation through Plate Tectonics Diamond Formation in Space What Are Diamonds Diamond formation occurs from the same element […]

Decay Chains is the name given to the stages of radioactive decay of unstable isotopes or elements. Some radioactive isotopes decay into stable isotopes directly but some unstable or radioactive isotopes decay into other unstable isotopes many times before becoming stable and these stages are explained in the ‘decay chain’. These decay chains can

Plants to animals Fossil Fuels Calcium Carbonate Our planet has got many systems or cycles in place that allow for the re-use of materials which are vital for life. These include nitrogen, water and carbon. The recycling of these vital materials helps support the continued existence of life that would otherwise end.
Boron is a relatively rare metalloid both on earth and in the rest Universe. It is produced from cosmic rays and extracted from Borate minerals.
