Natural materials come from plants, animals, and rocks, and include wood, cotton, leather, and metal. Man-made materials are produced through chemical processes applied to natural materials, such as plastic, synthetic cloth, and petroleum products. Man-made materials are generally more durable than earlier natural materials due to advances in chemical processing techniques.
