Fossil Fuel and Sedimentary Rock Formation

How are fossils and fossil fuels similar?

• Both are formed into solid rocks

• Both are formed from the remains of ancient plants and animals

• Triceratops rules, that's why!

• They are not similar

What needs to be present in the peat for fossil fuels to form?

• Sand and small pieces of wood

• Mostly decaying plants

• Mostly lava and sedimentary rocks

• Mostly minerals

Answer explanation

peat. noun. ˈpēt. : a dark brown or blackish material that is the remains of plants partly decayed in water and is sometimes dug up and dried for use as fuel.

Peat is the science word for "dead organic matter" 👍

The model below shows layers of sediment on the floor of an ocean. Which of the following best explains how these layers can become rock over many years?

• Sand in the sediment melts and turns into rock

• The weight of the water compacts the sediment into rock

• Changing water temperatures turn sand in the sediment into rock

• Pollution caused by humans turns the sediment into rock

Where does the sediment that forms sedimentary rocks come from?

• Sediments are formed by the cooling of magma

• Sediments are formed from the bones of dead fish

• Sediments are formed from decaying plant and animal matter

• Sediments are formed when rocks are broken down by weathering

Answer explanation

Always remember!! The first step of creating sedimentary rocks is the breaking down of bigger rocks! 😎

Answer explanation

Remember!! Most fossil fuels were formed in the ocean hundreds of millions of years ago!! 😁

Which of the following statements best describes compaction AND cementation?

Select two correct answers.

• Compaction happens when layers of rock press together.

• Compaction happens when rocks are weathered and eroded.

• Cementation happens when minerals stick the rock sediments together.

• Cementation happens when water covers layers of rock.

What process needs to occur over many years for sedimentary rocks to be completely formed?

• Evaporation and condensation from the water cycle

• Weathering of rock to break it apart

• Compaction and cementation to make sedimentary rock

• Heat and pressure to change the dead plants into coal
