Geysers
Why are fossil fuels nonrenewable resources?
They cannot be replaced within a short period of time.
They are natural resources.
They formed a long time ago.
They can be replaced easily.
Which fossil fuel is formed from the remains of plants that lived millions of years ago?
Oil
Natural Gas
Coal
Fire Wood
Sedimentary rocks are rocks made of __________.
soil
sediments
lime
shale
Decaying and decomposing are synonyms. What is another synonym for decay and decompose?
drop
carry away
sediments
dead
What takes longer to create?
Fossil Fuel
Sedimentary Rock
What could this environment form if the area is buried for a long time?
Natural Gas
Coal
Oil
Petroleum
The pictures show layers deposited on dead plants and animals. If millions of years past, what will most likely happen to the dead plants and animals?
They were eaten by scavengers
They become fossil fuels
They are washed away by water
They dissolve into the water
Select all that applies.
What 3 processes must occur in order for fossil fuels to form
Burial
Organism growth
Erosion
Earthquake
Compaction
How can plant from a pond form fossil fuels?
The dead plants sink to the bottom of the pond and get buried by sediments for millions of years.
The dead plants get compacted then cemented for millions of years.
The dead plants sink to the bottom of the pond and are consumed by decomposers
The dead plants produce carbon which forms fossils
What needs to be in the sediments in order for fossil fuels to form?
Sand and Wood
Decaying Organisms
Lava and Sedimentary Rocks
Metal Minerals
Students are learning about how fossil fuels are created in class. The student goes home and shares with his parents what he learned in school:
1. A long time ago, dead organisms die.
2. Then, layers of sediments are deposited on top of them.
3. The layers on top weigh down on the dead organisms and compacts them.
4. Finally, we have the fossil fuels we use today!
What should be added to the student's explanation to make it more accurate?
Change step 1 by adding that the organism is also decaying.
Change step 2 by adding that the organisms are buried under the sediments
Change step 3 by adding that Earth's core heats the dead organisms too
Change step 4 by adding that we have unlimited amount of fossil fuels to use
Which is NOT a type of fossil fuel?
Coal
Oil
Wood
Natural Gas
How old are fossil fuels?
Millions of years old
A few decades old
Hundreds of years old
They are new
Fossil Fuels also need an anaerobic environment, in order to form. What does that mean
High oxygen
No oxygen
wide open spaces
working out
What do fossil fuels need to form?
High pressure and low heat
High pressure and high heat
Low pressure and low heat
Low pressure and high heat
How is it that fossil fuels get their energy from the Sun?
Animals trap the Sun's energy and give it to fossil fuels.
The sun directly gives its energy to fossil fuels.
Fossil fuels absorb energy directly from the sun.
Plants absorb energy from the sun. Some animals eat those plants to gain energy. When the plants and the animals die, some get turned into fossil fuels.
Which fossil fuel is formed only from dead plants in swamps?
Rubber
Petroleum
Coal
Natural Gas
