Question

What are minerals ? on what basis are they identified? how they are useful for mankind?​

Answer 1

Answer:

Minerals are substances that are formed naturally in the Earth. Rocks are made of minerals. Minerals are usually solid, inorganic, have a crystal structure, and form naturally by geological processes. The study of minerals is called mineralogy.

Minerals can be identified by their unique physical properties: hardness, luster, color, streak, specific gravity, cleavage, fracture, and tenacity.

As minerals form rocks, they are very important.
