Copper is a chemical element with the symbol Cu and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. Copper is a transition metal and is the second most abundant element in the Earth’s crust, after oxygen. It is a major component of many industrial materials, including electrical wiring, plumbing, and roofing. Copper is also used in coins, jewelry, and art objects.
Coal is a fossil fuel formed from the remains of ancient plants that have been buried and subjected to intense heat and pressure over millions of years. Coal is a non-renewable resource, meaning that it cannot be replaced once it is used up. Coal is used to generate electricity, produce steel, and make chemicals.
Iron ore is a rock or mineral that contains iron. Iron ore is the primary raw material used to make iron and steel. Iron ore is found in many parts of the world, but the largest deposits are located in Australia, Brazil, China, India, and Russia.
Petroleum is a fossil fuel formed from the remains of ancient organisms that have been buried and subjected to intense heat and pressure over millions of years. Petroleum is a non-renewable resource, meaning that it cannot be replaced once it is used up. Petroleum is used to produce gasoline, diesel fuel, jet fuel, and other products.
