Explanation:
1) Natural resources are resources that are derived from nature and used without modification. All-natural resources, also known as sustainable resources, include the air we breathe, the water in our rivers and lakes, the soils, and minerals. It is divided into two categories: renewable and non-renewable resources. Non-renewable resources are those that require thousands of years to renew or replenish, whereas renewable resources are those that can be renewed or replaced fast.
2) The term "value" refers to the worth of anything. Some resources are economically valuable, whereas others are not. Metals, for example, have monetary value, yet a beautiful environment may not.
3) Non-renewable resources are those that must be renewed or replaced over thousands of years. Coal, petrol, and natural gas are examples.
4) Natural resources only become resources once they have been altered from their initial state. Iron ore was not considered a resource until it was discovered how to extract iron from it. Human-made resources include buildings, bridges, roads, machines, and cars, all of which are made from natural resources. Technology is a man-made resource as well.
