Natural
Resources
LESSON 2

2. NATURAL RESOURCES
•The things that we can find in
our environment that we use to
meet our NEEDS.
•These resources are not made
by humans or any scientific
experiments inside the
laboratories but they EXIST IN
NATURE.

3. TWO TYPES OF NATURAL RESOURCES
1.RENEWABLE
RESOURCES
• Are those that can be
replaced naturally
within the time the
supply is being used.
2.NONRENEWABLE
RESOURCES
• Are those that cannot be
replaced in a short period
of time because they take
millions of years to form.
Examples:
Air
Water
Plants
animals
Example:
Fossil fuels (Petroleum,
Coal, Natural gas)
Land
Metals
Nonmetals
