Modern Business Geography raising of beef cattle. We know that forests require a good rain- fall and will not grow where the cold is excessive. We even know under what conditions sea animals, such as codfish, thrive best. With the products of the mines, however, the case is different. Since few surface conditions help to explain their distribution under- ground, the search for them must often be carried on with relatively little guidance from science. Nevertheless the geologist is often able to locate ore bodies. Metals are usually found in mountainous regions or where mountains previously existed. This is partly because most ores are formed far beneath the earth’s surface, where intense heat and underground waters cause a concentration of metal-bearing com- pounds. Only when mountains are upheaved and worn away by rain and rivers are such ores exposed to our sight. But not all mountains contain metals. Because the distribution of metals is so irregular, it seems almost an accident that the Malay Peninsula and Bolivia produce most of the world’s tin; the United States and northwestern Europe, most of the world’s zinc ; Mexico and the United States, the silver ;: and the United States and Chile, the copper. THE MINERAL PRODUCTS The treasure that man digs out of the depths of the earth is of three kinds — metals, fuels, and stony products. The metals. Even in prehistoric times industry and art used the chief metals, — iron, gold, silver, copper, tin, lead. and zinc. There are many other metals; but only a few are of large commercial im- portance ; for example, aluminum, platinum, nickel, cobalt, iridium. The fuels. Heat is needed not only for cooking and for warmth, but for power and to work the metals. For many centuries it was obtained by burning wood. It was not until modern times that Europeans discovered that coal can be mined and used for heat, light, and power. Still more recently, deposits of petroleum and natural gas have been found and utilized. Stony products. In the earliest times man used stones as weapons and tools. Now he uses stone for buildings, pavements, and many other purposes, as well as vast amounts of clay, cement, sand, gravel, and other non-metallic minerals. 112 HOW THE MINERAL PRODUCTS ARE OBTAINED Metals and coal are mined in nearly the same way, by digging holes by which men can go down into the earth, get out what they seek, and bring it up to the surface. For petroleum and natural gas, deep wells are bored. and the oil or gas is carried off in pipe lines.
