The document discusses Earth's natural resources and how humans use and conserve them. It defines renewable and non-renewable resources, with examples like trees and water being renewable, while coal, petroleum and natural gas being non-renewable. It emphasizes the importance of conserving non-renewable energy resources since most come from the sun but renew slowly. Methods of conservation include using resources only when necessary, reducing waste, reusing and recycling materials, and preventing pollution of water and other resources.

2. I. Earth’s Resources – resources
that the Earth provides for
us.
A. Natural Resources –
natural material that are
used by humans.

4. 1. Examples – water, petroleum,
minerals, forest, and animals
2. Most resources are changed and
made into products that make
people’s lives more comfortable and
convenient
3. Energy we get from many of
these resources, such as gasoline and
wind, ultimately comes from the
sun’s energy!

5. The sun is the POWERHOUSE
 Would not have:
1. Trees
2. Wind
3. Fossil fuel
4. Plants
5. Animals

6. A. A renewable
resource is a natural
resource that can
be replaced at the
same rate at which
the resource is
used.
1. Examples:
Trees and water

7. A. A nonrenewable
resource is a
resource that forms
at a rate that is
much slower than
the rate at which it
is consumed.
1. Examples:
Coal, Petroleum,
and natural gas

8. Non-renewable does NOT mean that it doesn’t
renew.
It means the rate at which it renews itself is
SLOWER then the CONSUMPTION

9. A. Energy
Conservation –
most of the natural
resources that
provide us
energy are
nonrenewable
resources

11. 1. To conserve natural
resources, you should try to
use them only when
necessary.
a. Turn the faucet on only to
rinse you toothbrush
b. Turn lights off when you are
not using them
c. Make sure washing
machines are full before you
start them
d. Ride a bike, walk, or take a
bus

12. B. Reduce, Reuse, and
Recycle
1. Recycling – is the
process of reusing
materials from waste
or scrap. (Examples:
Newspaper,
Aluminum cans,
plastic, and
cardboard)
2. Though energy is
required to recycle
materials, it takes less
energy to recycle
than it does to make
new ones.

13. C. Conserving
resources also
means taking care
of the resources
even when you are
not using them
1. Keep lakes,
rivers, and other
water resources
free of pollution
