One of the most interesting facts about rhinoceroses is that they are descendants of some of the largest land animals to live on the planet. Prehistoric rhinos, called Indricotherium, stood over 17 feet tall at the shoul... More » Pets & Animals Mammals

A diamond is made entirely from carbon, the same element that makes up the graphite used in pencil leads. What gives a diamond the unique properties that differentiate it from common graphite is its physical structure. More »

The primary difference between diamond and graphite is the way their carbon atoms are arranged to form their physical crystal structures. The arrangement of carbon atoms in diamonds makes them bond together strongly, whi... More »

Powdered graphite is a soft, flaky, black mineral form of the element carbon that has been broken up into tiny particles, creating a powder. Powdered graphite is used as a solid lubricant and as an artist's pigment. More » Science Earth Science Geology

The molecular structure of a diamond makes it hard, as diamonds are comprised of carbon atoms linked closely together in a lattice structure. The atoms are linked tightly via covalent bonds wherein two atoms share an ele... More »
