NONRENEWABLE
AND
RENEWABLE
RESOURCES

NONRENEWABLE RESOURCES
A nonrenewable resource is a
natural resource that cannot be
re-made or re-grown at a scale
comparable to its consumption.

NUCLEAR ENERGY
Nuclear fission
uses uranium to
create energy.
Nuclear energy is
a nonrenewable
resource because
once the uranium
is used, it is gone!

COAL, PETROLEUM, AND GAS
Coal, petroleum, and
natural gas are
considered
nonrenewable
because they can not
be replenished in a
short period of time.
These are called
fossil fuels.

HOW ARE OIL AND GAS
MADE ???
Look at the info not the DATES

RENEWABLE RESOURCES
Renewable resources are
natural resources that
can be replenished in a
short period of time.
