Oil, coal, natural gas, metals, stone and sand are natural resources. Other natural resources are air, sunlight, soil and water.
What are most natural substances?
Most natural substances are complex mixtures of compounds belonging to various chemical substance classes, e.g. alkaloids, lipids, peptides, phenolics, sugars, terpenes [2-4]. The compositions of these mixtures derived from a certain species can vary.
What are the two types of 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?
Natural material
- Biotic materials. Wood (rattan, bamboo, bark, etc.) Natural fiber (silk, wool, cotton, flax, hemp, jute, kapok, kenaf, moss, etc.)
