introduction
The united states has many resources. Some of the most productive farmlands in the
world are found inthe interior plains
California,florida,texas, and other states supply oil and natural gas
coal and other minerals are found in appalachian and western states
How many resources are in the united states?
Coal Copper Lead Molybdenum Phosphates uranium
Bauxite Gold Iron Mercury Nickel Potash. etc...
They are 18, and this are
What is coal?
Coal is acombustible black or brownish-black sedimentary rock normally occurring in rock strata in layers or veins called coal beds or coal seams
What is copper?
Copper is a reddish brown nonferrous mineral which has been used for thousands of years by many cultures
What is lead?lead is a main-group
element in the carbon group with the symbol Pb and atomic number 82. Lead is a soft, malleable poor metal.
What is molybdenum? Molybdenum is a metallic element used
primarily as an alloy in steel manufacturing
What is nickle?Nickel is a chemical element
with the chemycal symbol Ni and 28.is a silvery-white lustrous metal with a slight golden tinge.. nickel belongs to the transition metals and is hard and ductile
What is potash?Potash is athe common
name for various mined and manufactured salts that contain potassium In water-soluble form. In some rare cases, potash can be formed with traces of organic materials such as plant remains,
and this was the major historical source for it before the industrial area.
What is silver?
Silver is a metallic chemical element with the chemical symbol Ag , and atomic number 47. A soft, white, lustrous tansition metal, it has the highest electrical condictivity of any element and the highest thermal conductivity of any metal
What is tungsten?
tungsten A hard, rare metal under standard conditions when uncombined, tungsten is found naturally on Earth only in chemical compounds.
What is zync?Zinc It is the first element in
group 12of the periodic table. Zinc is, in some respects, chemically similar to magnesium, because its ion is of similar size and its only common oxidation state is +2
What is photophate?
A phosphate, an inorganic chemycal, is a salt of phosphric acid. In organic chemistry, a phosphate, or organophosphate, is an ester of phosphoric acid

Iron is a chemical element with the symbol Fe , and atomic number 26. It is a metal in the first transition series. It is the most common element forming the planet Earth as a whole, forming much of Earth's outher and inner core
What is mercury?
Mercury is a chemical element with the symbol Hg and atomic number 80. It is also known as quicksilver or hydrargyrum
What is pretoleum?petroleum or crude oil is a naturally occurring, consisting
of a complex mixture of hydrocarbons of various molecular weights and other liquid organic compounds, that are found in geologic formations beneath the earth's surface.flammable liquid
What is natural gas?Natural gas is a naturally occurring gas mixture
consisting primarily of methane, typically with 0–20% higher hydrocarbons
Conclusion The conclusion is that the natural
resources are very important and usefull
