Natural Resources
Natural resource

Natural resources provide materials and
energy. A natural resource is any energy
sources, organism, or substance found in
nature that people use.
There are two categories of
resources: Renewable and
Nonrenewable resources
Renewable resource

A renewable resource is
a natural resource that
can be used and replaced
over a relatively short
time.
Types of Renewable Resources


Nuclear energy is an alternative source of
energy from the nuclei of atoms.
Fission and Fusion are types of nuclear
energy. (Fission-splits atoms & Fusion-joins
atoms)

Sunlight (Solar Energy) is energy from the
Sun. Everyday, the Earth receives more
than enough solar energy to meet all our
energy needs.

Wind (Wind turbines)- are technological
updates of the old windmills and generate
significant amounts of electricity. Wind is
created by the uneven heating of air by the
Sun.

Water (Hydroelectric energy) is electricity
produced by falling water.

Trees and other plants, animal waste
(Biomass) is organic matter that contains
stored energy. The most common way of
releasing the energy is burning the biomass.

Earth (Geothermal) energy is energy from
within the Earth. Buildings in Iceland are
heated by this energy in their country’s
many geothermal sites.
Nonrenewable resource

A nonrenewable resources made from
once-living plants and animals that were
buried in Earth’s crust for millions of years.
Fossil fuels supply most of society’s
nonrenewable energy.
Types of Nonrenewable Resources

A fossil fuel, such as coal, oil, or natural
gas are all a nonrenewable resources.
Fossil fuels burn easily and give off a lot of
heat. However, there are disadvantage to
their use. In addition to being
nonrenewable, fossil fuels produce
pollution when they are burned and can
harm the environment in other ways, such
as through oil spills.
Examples of nonrenewable resources are:
 Coal (ancient plant from a swamp)
 Oil (flammable organic compound)
 natural gas (can be separated by humans)
 uranium ("burned" in nuclear power
reactors)
 minerals and rocks (naturally made
material)
Methane
petroleum
Coal
Results of Nonrenewable Resources

Acid precipitation is rain or snow that has
high acid content due to air pollutants. Acid
precipitation negatively affects wildlife,
plants, buildings and statues.

Smog is a
photochemical fog
produced by the
reaction of sunlight and
air pollutants. Los
Los
Angeles
Denver
Angeles and Denver have
serious smog issues because
of the abundance of sunshine
and cars surrounded by
mountains.
Way to Conserve

Recycling is the process by
which used or discarded
materials are treated for reuse.

Reduce is to make something
smaller or use less, resulting in a
smaller amount of waste.
Reuse material in their original form
instead of throwing them away, or
pass those materials on to others
who could use them too!
