Question

what is mean bynatural and man-made material

Answer 1

Some materials grow - cotton comes from a plant, and wool comes from sheep. But some materials are man-made. They are made from other things. In science we can divide products and materials into natural and man-made.

Answer 2

A man-made material is one that is manufactured through human effort. These materials are usually made using natural, raw materials. Examples of man-made materials are glass, rayon and nylon

Natural resources are made by the Earth only, and they are useful to humans in many ways. They can be biotic, such as plants, animals, and fossil fuels; or they can be abiotic, meaning they originate from nonliving and inorganic materials.
