GEOLOGY

Detailed explanation-1: -Minerals-A mineral is composed of the same substance throughout. There are about 3000 different minerals in the world. Minerals are made of chemicals-either a single chemical or a combination of chemicals. There are 103 known chemical elements.

Detailed explanation-2: -There are over 3000 minerals known to exist in the earth’s crust. About 100 of these are considered to be “common.” Most rocks are made out of more than one mineral, although a rock may be made out of just one mineral.

Detailed explanation-3: -Scientists can distinguish more than 4, 000 different minerals but many are very rare. About 200 minerals make up the bulk of most rocks. The feldspar mineral family is the most abundant. Quartz, calcite, and clay minerals are also common.

Detailed explanation-4: -More than 4, 000 naturally occurring minerals-inorganic solids that have a characteristic chemical composition and specific crystal structure-have been found on Earth. They are formed of simple molecules or individual elements arranged in repeating chains, sheets, or three-dimensional arrays.

Detailed explanation-5: -A mineral is a naturally occurring substance with distinctive chemical and physical properties, composition and atomic structure. Rocks are generally made up of two of more minerals, mixed up through geological processes.
