Minerals

How Some Minerals Form mineral: always a solid material with particles arranged in a repeating pattern the pattern is called a crystal almost all minerals are made from material that was never alive true minerals only form in nature

the pattern is called a crystal

almost all minerals are made from material that was never alive

true minerals only form in nature

diamonds form in Earth’s mantle high heat and pressure change carbon into hard, sparkling crystals called diamonds diamonds have many uses some are cut and shaped to make jewelry most are used on cutting tools such as drills and saws

calcite can form near Earth’s surface calcite can form in the ocean when calcium, oxygen, and carbon combine in sea water some ocean animals form calcite shells or other body parts calcite also forms as water evaporates in limestone caves

galena crystals form when hot, mineral rich water moves slowly through cracks in Earth’s crust, mixing with other minerals before it cools and evaporates

Some Mineral Properties streak: color of the powder left behind when you rub a mineral against a white tile called a streak plate usually the streak is the same color as the mineral chalcopyrite looks shiny black but streaks gold

usually the streak is the same color as the mineral

chalcopyrite looks shiny black but streaks gold

luster: the way the surface of a mineral reflects light some minerals look shiny - metallic luster some minerals look dull/dark - nonmetallic luster sparkling appearance of a diamond is known as a brilliant luster hardness: a mineral’s ability to resist being scratched Moh’s hardness scale lists minerals that have hardness from 1 to 10 a mineral with a higher number can scratch a mineral with a lower number

How We Use Minerals some minerals can be used in the same form as they have in nature silver and copper can be used to make musical instruments, electric wire, jewelry gypsum can be used to make plaster and wallboard graphite can be used in pencils halite (table salt) can be use to flavor and preserve food

silver is a soft metal hardness of 2 mixed with other metals to make jewelry or musical instruments hematite is made of iron and oxygen hardness of 5 - 6.5 important source of the iron used to make steel steel beams used to make tall buildings strong diamond is the hardest natural substance found on Earth hardness of 10 used to make jewelry diamonds not good enough for jewelry used on drills that dig deep into Earth’s crust

some minerals are not useful in their natural form need to be refined cuprite is made of copper and oxygen when cuprite is refined the copper is used in pennies, pots, pans, and water pipes

Summary some minerals form in Earth’s mantle and others form at or near the Earth’s surface minerals can be identified by their properties streak, hardness, and luster minerals have many uses
