Define mineral resource and list two major types of such resources. Describe three uses of rock as a resource. Define ore and distinguish between a high-grade ore and a low-grade ore. What are reserves? Describe the life cycle of a metal resource. Describe three major harmful environmental effects of extracting, processing, and using nonrenewable mineral resources.

A mineral resource is an area in which there is a significant concentration of a solid resource with an economic value.

Explanation:

Two major types are: metallic like gold and silver and non - metallic like sand and gravel.

Rocks can be used for building, cosmetics, dyes, appliances, etc.

An ore is an area that is full of minerals with an economic value like cupper. There are two kinds of them. A high - grade ore is the one that contains a significant high value of the mineral, for example, in gold, is there is an ore with 5 g/tonne or more is consider with a high - grade. A Low - grade ore is the one that shows some concentration of the mineral but in low concentrations that is not worth to be ex tractable.

Life cycle of a metal resource is referring to all steps that human need to do to obtain the mineral like extracting, processing, and using the resource. During all this process, since it is used a lot of energy, there is some erosion to soil, also there are production of solid wastes, and pollution of water and air by the tiny particles that are produced trough all the process.

Hope this info is useful.
