This endangered mandrill (Mandrillus sphinx) was photographed by National Geographic Photographer Joel Sartore on Bioko Island, Equatorial Guinea, in his ambitious project to document every species in captivity—inspiring people not just to care, but also to help protect these animals for future generations. Before drills disappear, like this webpage has, learn how …

Petroleum can be contained by structural traps, which are formed when massive layers of rock are bent or faulted (broken) from Earth's shifting landmasses. Oil can also be contained by stratigraphic traps .

Social media is a newer form of mass communication. People access social media sites on the internet through personal computers and cellphones. Internet users access sites like Instagram, Twitter, and Facebook to post photographs, videos, stories, opinions, and more to an audience of followers.

Ore is a deposit in Earth's crust of one or more valuable minerals. The most valuable ore deposits contain metals crucial to industry and trade, like copper, gold, and iron. Copper ore is mined for a variety of industrial uses. Copper, an excellent conductor of electricity, is used as electrical wire. Copper is also used in construction

Ore is a mineral aggregate mined from an ore body from which useful components (elements, compounds, or minerals) can be extracted under existing technical and economic …

Ore Geology is the field which covers major aspects pertaining to the description, understanding and genesis of the ore deposits. Broadly, Ore Geology is the study of the formation and …

The various theories of ore genesis explain how the various types of mineral deposits form within the Earth's crust. Ore genesis theories are dependent on the mineral or commodity. Ore genesis theories generally involve three …

What are fossil fuels? How were they formed? Learn how human use of non-renewable energy sources, such as coal, oil, and natural gas, affect climate change.

Surface mining can be destructive to the surrounding landscape, leaving huge open pits behind. In underground mining, ores are removed from deep within the earth. Miners blast tunnels into the rock to reach the ore deposits. This process can lead to accidents that trap miners underground.

Mineral deposits form because some medium serves as a concentrating and transporting agent for the ore minerals, and some process subsequently causes the transporting agent to precipitate, or deposit, the minerals.

Ores are classified based on how they form. Some ores form from the cooling and crystallization of minerals within magmas, lavas, or igneous intrusions, some are formed by sedimentary processes and some are formed …

Deposits of minerals form when a medium that contains and transports mineral-making ore releases and deposits the ore. Magma is one such medium that transports ores. When magma or lava cools, the magma and ore carried within it crystallize to form tiny minerals in the newly created igneous rock .

Nuclear energy comes from radioactive elements, mainly uranium, which is extracted from mined . ore and then refined into fuel. Unfortunately, human society is—for the time being—dependent on nonrenewable resources as its primary source of energy.

New computer simulations by geologists from ETH Zurich demonstrate how large copper and gold deposits are formed. The enrichment process of these metals follows physical principles that are similar to the extraction of deep geothermal …

Ore is a deposit in Earth's crust of one or more valuable minerals. The most valuable ore deposits contain metals crucial to industry and trade, like copper, gold, and iron. Copper ore is mined for a variety of industrial uses. …

Igneous Rocks Igneous rocks (derived from the Latin word for fire) are formed when molten hot material cools and solidifies. Igneous rocks can also be made a couple of different ways. When they are formed inside of the earth, …

Deposits of ore are created through something called ore genesis. Ore genesis takes millions of years. For this reason, Earth contains only a limited amount of ore.

Ore bodies are formed by a variety of geological processes. The process of ore formation is called ore genesis. Various theories of ore genesis explain how the different types of mineral deposits in the Earth's crust have been formed.
