What are most natural substances?

What is the hardest natural substance?
While diamonds may be the hardest naturally occurring substance found on earth, he explains, they are not the hardest available (there are two harder substances – a laboratory synthetic nanomaterial called wurtzite boron nitride and a substance found in meteorites called lonsdaleite).
What are man made substances?
A man-made substance is created from natural resources. You put them through a chemical reaction and transform them into something brand new. This reaction could be melting them using extremely hot temperatures, or mixing in other substances, or both!
What are three examples of natural materials?
- Biotic materials. Wood (rattan, bamboo, bark, etc.) Natural fiber (silk, wool, cotton, flax, hemp, jute, kapok, kenaf, moss, etc.)
- Inorganic material. Stone (flint, granite, obsidian, sandstone, sand, gems, glass, etc.) Native metal (copper, iron, gold, silver, etc.)
