  1. 1. NONRENEWABLEANDRENEWABLERESOURCES
  2. 2. NONRENEWABLE RESOURCESA nonrenewable resource is anatural resource that cannot bere-made or re-grown at a scalecomparable to its consumption.
  3. 3. NUCLEAR ENERGYNuclear fissionuses uranium tocreate energy.Nuclear energy isa nonrenewableresource becauseonce the uraniumis used, it is gone!
  4. 4. COAL, PETROLEUM, AND GASCoal, petroleum, andnatural gas areconsiderednonrenewablebecause they can notbe replenished in ashort period of time.These are calledfossil fuels.
  5. 5. HOW IS COAL MADE ???
  6. 6. HOW ARE OIL AND GASMADE ???Look at the info not the DATES
  7. 7. RENEWABLE RESOURCESRenewable resources arenatural resources thatcan be replenished in ashort period of time.● Solar Geothermal●● Wind Biomass●● Water
