Ch. 10 Lesson 1What are nonrenewable

energy resources?

resource

supply that will meet a need for

materials or energy2 types

1. renewable

2.nonrenewable

1. renewable

can be replaced

ex: trees

2. nonrenewable

cannot be replaced or cannot be replaced as fast as we use it

fossil fuelscoal, petroleum (crude oil), natural gas

Natural Resources [07:06]

The energy from fossil The energy from fossil fuels comes from fuels comes from

sunlight.sunlight.

coal1. forms from swampy plants

2. layers of dead plants build up

3. decaying material forms peat

4. peat gets buried

5. soft coal hard coal

• releases sunlight energy from plants

• fuels most electric power plants

Many U.S. coal beds are very near the ground's surface, and about

two-thirds of coal production comes from surface mines.

Chocolate chip mining

• Coal is extracted from the Earth’s crust through a process called mining.

• Once mining engineers have discovered, extracted and prepared the coal, they can be used to make energy.

Chocolate chip mining

Instructions

1. Take one cookie and pretend it is an environment in which a great source of energy (coal) has been located (chocolate chips).

2. Predict how many chips you can extract from this environment.

Instructions3. Using your mining tools

(toothpicks), extract as many chips as possible before your mining lease expires (in 2 minutes) and pile them to one side.

4. Count the chips you recovered and compare this with the number of chips you predicted.

Instructions

5. Now study the impact of your mining on your "cookie" environment. What do you think would happen if this were a real coal mine? What if animals and plants lived above the coal deposits? What might happen to them after the mining has taken place?

6. Now think of ways to mine the second cookie with less damage to the environment.

Instructions

7. Take the second cookie and mine it using the ideas you came up with to protect the cookie environment. Pile the new chips to one side.

8. Compare the two piles of chips. How did you do the second time?

formed same as coal except buried tiny sea organisms instead of plants

fossil fuels

made from the remains of organisms

1. easy to store & transport

2. more energy than other resources

1. supplies are limited

2. cause pollution

Fossil Fuels [00:51]

Fossil fuels are made from the remains of organisms.

Fossil fuel is easy to store.

Fossil fuel is easy to transport.
