6. True or false? The more heat and pressure coal experiences
while it is formed, the less energy contained in the coal.
__________
7. Explain how coal is used to generate electricity.
8. Natural gas can be formed two different ways.
___________________ gas is created at shallow depths

Impacts of Fossil Fuels
Dear EarthTalk: What, if anything,
fills the empty space underground
created by the extraction of billions
of gallons of oil? Could oil drilling
be one of the causes of increasing
amounts of land settling and
sinkholes in oil rich areas? Can it
cause earthquakes? – Linda

HW #18
The crude oil (and natural gas) we drill for the world over
is, for the most part, stored in tiny pores within rock up
to only about three miles deep in the Earth’s hugely
dense crust. At such depths, the oil there is under fairly
high pressure. When it is removed, other liquids—
usually water—move in to take its place, equalizing the
pressure in the process. Sometimes oil extractors
pump water into one side of an oil field to push oil
toward wells on the other side, and the water replaces
the oil accordingly. In cases where other liquids don’t
move in, such as in the North Sea off The Netherlands,
the porous rock layer that harbored the oil originally can
collapse after extraction, causing slight amounts of land
settling (known as “land subsidence”) in the rock layer
surfaces above

HW #18
How can you mine the most
“coal” without damaging the
mountain?
1) Weigh your “mountain” on the balance
2) Use your tools (tweezers) to extract as many
pieces of “coal”
3) Make as little damage to your environment as
possible!
Afterwards, we will weigh your “mountain” again and “coal”
to see how much mass you lost and how much “coal”
you mined.
(prize to the group that mines the most coal while
damaging the mountain the least!)
