Full Answer

Rocks can broadly be classified into three categories: sedimentary, igneous and metamorphic rocks. These classes, which are based on the rock's origin, determine the structure and use of the rock.

Rocks are important in the making of many objects, such as plates, jewelry and toothpaste. Most houses are also built of materials obtained from rocks. Some of the most valuable rocks used in the manufacturing of items include graphite, slate, limestone, gypsum and pyrite. These types of rocks help in the production of stationery and the building of houses. Coal, which is an organic rock made mainly from plant materials, has various uses. It can be used in the production of gas, and its residue is used in making plastics and several synthetic materials.

Rock mining provides employment opportunities for casual workers, especially in places where formal jobs are difficult to find. Rocks contribute greatly to the economy of a country or region where they are found. Rocks are also used in the medicine industry. Bismuth is helpful for people with stomach upsets, while silver is used in the manufacturing of dental equipment.

  • Q:

    What are the similarities and differences between rocks and minerals?

    A:

    Rocks and minerals are inorganic compounds and occur throughout the world but have distinct physical characteristics, distinguishing features and societal uses that set them apart. Minerals are generally lighter in weight and color than rocks and hold value for their aesthetic properties. Rocks, in contrast, are denser, darker and hardier and find use in the industrial and construction industries.

  • Q:

    How are rocks different from minerals?

    A:

    Rocks are different from minerals in that minerals are single crystalline accumulations of one or more elements, while rocks are solid accumulations of one or more minerals. Rock can either refer to a particular, detached object or, in a general sense, as a synonym for stone, generally referring to a portion of the substance. Individual minerals can be obvious in rocks, as with granite, or microscopic, as with many basalts.
