Rocks have a broad range of uses that makes them significantly important to human life. For instance, rocks are used in construction, for manufacturing substances and making medicine and for the production of gas. Rocks are also extremely vital to scientists as they provide clues about the Earth’s history.Know More
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.Learn more about Geology
The most common type of igneous rock, basalt, also known as malfic rock, can be found on oceanic plates at divergent plate boundaries. Intermediate and felsic igneous rocks show up along continental margins, as well. Because igneous rocks form from the cooling of lava and magma, they can be found around areas where volcanic activity is or has been present.Full Answer >
Rock is the primary component of the Earth's crust. Although soil, sand and other natural materials are similar to rocks, they are not actually rocks and are classified as derivatives of rocks. Minerals are necessary to form nearly all types of rock, and most include more than one mineral. Metals are also found in many rock types.Full Answer >
Rocks are formed in three primary ways, and each method produces rocks with different characteristics. Rocks are either classified as sedimentary, igneous or metamorphic, depending on the manner in which they were formed. Most rocks encountered in everyday life are sedimentary, although some igneous rocks, such as granite, are also common.Full Answer >
Humans use rocks for a wide variety of purposes, including construction and as a source of valuable minerals located inside the rocks. Additionally, humans use rocks for decoration, recreation and thermal purposes. Humans are not the only organisms that utilize rocks, as plants, animals and fungi use rocks for stability, digestive purposes and as a substrate.Full Answer >
