Maybe stones were first used as curiosity pieces, maybe as weapons, but ultimately, they were used as tools. This was the Paleolithic Period , the beginning of geologic study, and it dates back 2. In fact, all things we use come from only three sources: they are farmed, hunted or fished, or mined. At the turn of the twentieth century, speculation was rampant that food supplies would not keep pace with world demand, suggesting the need to develop artificial fertilizers. Sources of fertilizer ingredients are: nitrogen is processed from the atmosphere , using the Haber process for the manufacture of ammonia from atmospheric nitrogen and hydrogen; potassium comes from the hydrosphere , such as lakes or ocean evaporation; and phosphorus is mined from the lithosphere , such as minerals like apatite from phosphorite rock, which is found in Florida, North Carolina, Idaho, Utah, and around the world. Thus, without mining and processing of natural materials, modern civilization would not exist. Indeed, geologists are essential in this process.

As each of us use the Earth's natural resources on a human time scale, it is important to consider that mineral resources form on geologic timescales, and the vast difference between the two. The items in this case are just a few of the ways that we use rocks and minerals in our everyday lives. Production of this gallery was generously supported by The Ford Family Foundation. Gypsum is ubiquitous in our lives as the basis for drywall. It contains water in its mineral structure, which it loses when heated, providing an initial line of defense against building fires. In the time before dry-erase boards, all education relied upon chalkboards made from slate, which is clay that has been cooked by heat and pressure deep within the earth. Chalk is a limestone made of the skeletons of millions of microbes that once lived at the bottom of the sea , so it's really a fossil. Ceramics, from simple plant pots to extravagant porcelain, are made from clay mudstone. That's just a rock that forms from the compaction of mud. If it's buried deep enough, it becomes slate. Granite and marble counter tops are made from stone. Granite forms when magma cools within the earth and never erupts from a volcano. The slower it cools, the larger the mineral grains that form.

Mining is the extraction of valuable geological materials and minerals from the surface of the Earth. Mining is required to obtain most materials that cannot be grown through agricultural processes , or feasibly created artificially in a laboratory or factory. Ores recovered by mining include metals , coal , oil shale , gemstones , limestone , chalk , dimension stone , rock salt , potash , gravel , and clay. The ore must be a rock or mineral that contains valuable constituent, can be extracted or mined and sold for profit. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, and final reclamation or restoration of the land after the mine is closed. The exploitation of these deposits for raw materials is dependent on investment, labor, energy, refining, and transportation cost. Mining operations can create a negative environmental impact, both during the mining activity and after the mine has closed.

Millions of years ago, algae and plants lived in shallow seas. After dying and sinking to the seafloor, the organic material mixed with other sediments and was buried. Over millions of years under high pressure and high temperature, the remains of these organisms transformed into what we know today as fossil fuels. Coal , natural gas , and petroleum are all fossil fuels that formed under similar conditions. Today, petroleum is found in vast underground reservoirs where ancient seas were located. Petroleum reservoirs can be found beneath land or the ocean floor. Their crude oil is extracted with giant drilling machines. Crude oil is usually black or dark brown, but can also be yellowish, reddish, tan, or even greenish.

The most active hydrothermal process today produces volcanogenic massive sulfide VMS deposits, which form from black smoker hydrothermal chimney activity near mid-ocean ridges all over the world. Mining, concentrating, smelting, and refining processes require enormous energy.

When the industries thrive, the larger companies manage extensive research programs that foster close links between exploration projects and scientists from government and universities. In , the World Bank began to push for privatization of government-owned mining companies with a new set of codes, beginning with its report The Strategy for African Mining. Artisanal gold mines near Dodoma, Tanzania.

Before you can learn about plate tectonics, you need to know something about the layers that are found inside Earth. These layers are divided by composition into core, mantle, and crust or by mechanical properties into lithosphere and asthenosphere. Rocks yield some clues, but they only reveal information about the outer crust.

The water was used for a variety of purposes, including removing overburden and rock debris, called hydraulic mining , as well as washing comminuted , or crushed, ores and driving simple machinery.

At the same time, toxic chemicals and dangerous pathogens can seep into water supplies. Asbestos [image left] has an unsavory reputation for causing cancer in people who work around it. Rare Earth Elements lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium ytterbium and lutetium Many of these are used to create nuclear power. Mining and processing of mined materials typically increase the surface area to volume ratio in the material, causing chemical reactions to occur even faster than would occur naturally. It is also used to make certain acids, in fire extinguishers and melting ice on the road. All of the rubber and plastics here are made from oil, including the gas can. Deep green is the most desired color in Emeralds. But over the past two centuries, geologists have become increasingly aware that divisions between solid, liquid, and gaseous environments can be unnecessarily restrictive.
