Using Natural Resources
• Natural ResourcesAny material in
nature that people
use and value
 Examples: air,
water, soils,
forests, and
Types of Resources
 Renewable Resources- Resources Earth replaces
 Examples: water, soil, trees, plants and animals
 Nonrenewable Resources- Resources that cannot
be replaced
 Examples: coal, oil, natural gas
Nonrenewable Energy
 Main source to generate electricity, power vehicles, and
generate electricity
 Reliable source of energy but causes pollution
 Energy generated from power plants is lost through
power lines
Renewable Energy Sources
 Produce little to no pollution
 Cheaper to maintain and use
 Not as reliable as fossil fuels due to weather conditions
and energy being produced
Energy Resources
 Fossil Fuels- Non renewable resources that formed
from the remains of ancient plants and animals
 Ex: Coal, petroleum, and natural gas
 Hydroelectric power- The production of electricity
from water power
 Ex: Dams, water turbines
Managing Natural
• DeforestationClearing of trees
• ReforestationPlanting trees to
replace lost
Efforts to Conserve
 Important to protect natural resources
 Recycling helps reuse resources that aren’t renewable
 More efficient ways to harness renewable resources
Resources and Daily Life
 Affects people lifestyles and needs
 Places with fewer natural resources have fewer choices
and different needs
 Ex: Food, clothing, transportation, and entertainment
Resources and Wealth
 Some places profit off of natural resources
 Saudi Arabia is rich with oil
 Countries with large amount of resources are usually
richer than those countries who have fewer
