NATURAL RESOURCES RENEWABLE OR NON-RENEWABLE ? ? ?

NON-RENEWABLE • A non-renewable resource cannot be easily/quickly replaced naturally • There is a limited supply ( can use up the entire supply until there is no more)

MINERALS • Precious stones: rubies, diamonds, emeralds, • Metals: gold, silver, copper, lead, iron. .

FOSSIL FUELS • Fossil fuels are organic materials formed in the earth as a result of slowly decomposing plants and animals. It takes millions of years to obtain fossil fuels!

RENEWABLE • A renewable resource can be easily/quickly replaced naturally • There is an un-limited supply as long as it is not being abused/over-used

Wind Energy • Wind power is the use of air flow through wind turbines to mechanically power generators for electric power.

Biomass Energy • Biomass is organic material that comes from plants and animals, and it is a renewable source of energy. Biomass contains storedenergy from the sun. Plants absorb the sun's energy in a process called photosynthesis. When biomass is burned, the chemicalenergy in biomass is released as heat.

Water Energy (hydroelectricity)

Trees (for lumber)
