Is plastic man-made or natural?
Plastics typically are made through human industrial systems. Most modern plastics are derived from fossil fuel-based chemicals like natural gas or petroleum; however, recent industrial methods use variants made from renewable materials, such as corn or cotton derivatives.

Utilising natural resources. Natural resources are the raw materials supplied by the earth. These resources include soil, air, water, sunshine, forests, wildlife, fish, fossil fuels, metals and minerals. Using natural resources to meet human needs has an impact on global environment.
How are metals found in nature?
Only gold, silver, copper and the platinum metals occur in nature in large amounts. Over geological time scales, very few metals can resist natural weathering processes like oxidation, which is why generally only the less reactive metals such as gold and platinum are found as native metals.
What is the material that cannot be into simpler materials?
An element is always uniform all the way through (homogeneous). An element cannot be separated into simpler materials (except during nuclear reactions). Over 100 existing elements are listed and classified on the Periodic Table .
What is nature of raw material?
Natural raw materials are any resources that are found in nature and that will be used to make manufactured goods. There are many different types of raw materials that are regularly used in this manner, including rocks and minerals, plants, oil, natural gas, and animal products.
