Metal ores are one of the Earth's most common minerals. Metals are useful in all types of industry because they last a long time, are conductors of electricity, and can be easily shaped. Since the first metal alloy was created more than 6,000 years ago during the Bronze Age, people have recognized the potential of extracting metallic elements from rock. Metals traces the history, uses, methods of extraction, and future of one of our most versatile resources. Topics include: early use of metals during the Bronze Age, the Iron Age, and the Copper Age which countries have the most deposits of metal ores, and how much metal different countries use extracting metals from ores by use of smelting, flotation, and leaching the equipment that geologists use to locate metal deposits in ore the lives of miners, including their working conditions, the equipment they use, and the dangers that they encounter working in open-pit and underground mines the role that recycling plays in saving our environment and how metals are recycled

Minerals are chemicals that are the building blocks of rocks. Metals, crystals, and gemstones are all minerals found in rocks. This interesting book describes how to identify minerals, where they can be found, the rock cycle process, the uses of minerals, and how they are mined.
What is the Rock Cycle describes the natural transformation of one type of rock into others. Beginning with igneous rocks made in volcanic eruptions, rock is weathered and eroded gradually to form a sediment. This sediment is then deposited and pressed into layers making sedimentary rocks. These in turn are transformed by heat and pressure into metamorphic rocks. Heat makes these melt into magma which, together with molten rock from the core of the Earth, make new igneous rocks.
It all starts with erosion for sedimentary rock. Worn down bits of rock become pressed together under pressure into strata, or layers. The formation of rock such as sandstone, shale, limestone, and dolomite is explained in this fact-filled book. Readers will also learn that this type of rock is useful in determining the Earths geological history because its layers often hold fossils and other geological clues.
Crystals are made up of minerals hardened into distinct shapes with regular repeating patterns. This informative book takes a look at the underground process that creates crystals, from sparkling quartz to ordinary salt, as well as where they are found and how they are mined.
