These are resources used in the process of production. They are necessary for the production of goods and services, which are used by human beings to satisfy their needs. There are four types of resources:

Human resources

Non-renewable resources include mineral deposits such as gold, silver, platinum, coal, petroleum, iron ore, bauxite, copper, zinc, lead, magnesium, etc. which exist in finite quantities in the earth's crust and therefore are of diminishing supply.

Indestructible resources include land, in the sense of two-dimensional space necessary for habitation, and carrying out of economic activities. Land is employed here in its capacity to provide space rather than to grow crops on its soil.
