Oil formation starts when organisms in the ocean die and then –
get eaten by larger organisms that receive their energy
are carried by currents all over the planet
decay completely so that their matter is recycled.
settle to the bottom and are buried in sediments
The formation of fossil fuels is a process that takes millions of years and starts with energy from the Sun. The Sun contributes to the formation of fossil fuels by –
heating up the Earth's core where fossil fuels form.
generating winds, so humans use less fossil fuels.
giving energy to the living things that become fossil fuels.
giving off heat, similar to burning fossil fuels.
What conditions in an ancient environment would make it suitable to the formation of fossil fuels?
Movement of surface water causing weathering of rock.
Frequent volcanic eruptions and forest fires.
Extremes in high and low temperatures during the day.
Abundant plant life and rapid laying down of sediments.
12. What is similar in the formation of many sedimentary rocks and all fossil fuels? Many sedimentary rocks and all fossil fuels….
require material to be buried and exposed to heat and pressure.
are made from decayed plants and animals that stores the Sun’s energy.
form where there are frequent earthquakes and volcanic activity.
are produced high in the mountains where temperatures are low.
Most sedimentary rock forms in oceans. This is because oceans....
emit less pollution
receive more of the sun's energy
have fewer plants and animals
are where sediments get deposited
Sedimentary rocks form when broken bits of other rock are deposited and then –
buried and squeezed and cemented together
melted by heat from Earth's core
dissolved in the ocean water
used by humans as a natural resource
What changes buried organic matter into fossil fuels?
industrial pollution
volcano eruptions
ocean currents
heat and pressure
