Sedimentary Rocks
Formed when layers of sand, mud, and small rocks are pressed together over time.
What is a sedimentary rock?
The preserved remains or traces of a living organism.
What is a fossil?
A natural fuel formed from ancient plants and animals.
What are fossil fuels?
The process of breaking down rocks into smaller pieces.
What is weathering?
Fossil fuels provide this because they produce a lot of power.
What is high energy?
The process where sediments are squeezed together to form rock.
What is compaction?
Layers of rock that form over time from deposited sediments.
Answer: What are rock layers (strata)
This fossil fuel is a solid and is often used to generate electricity.
What is coal?
The movement of sediments from one place to another.
What is erosion?
Burning fossil fuels releases this harmful gas into the air.
What is carbon dioxide?
The process where minerals glue sediments together.
What is cementation?
New layers of sediment are usually found on this part of rock layers.
What is the top?
This liquid fossil fuel is refined into gasoline.
What is oil (petroleum)?
The dropping off of sediments in a new location.
What is deposition?
This is an advantage of fossil fuels related to availability.
What is easy to find or use?
These rocks often form in layers and may contain fossils.
What are sedimentary rocks?
Older layers of rock are usually found in this part.
What is the bottom?
This fossil fuel is a gas used for heating and cooking.
What is natural gas?
Layers of sediment build up over time to form this.
What are rock layers (strata)?
This is a disadvantage because fossil fuels can run out.
What is nonrenewable?
why can a sea shell be found on a mountain?
{Explain}
This process causes layers of sediment to build up over time.
What is deposition?
Fossil fuels are considered this type of resource because they take millions of years to form.
?
What is nonrenewable?
Heat and pressure over millions of years help form this from dead organisms.
What are fossil fuels?
Using fossil fuels can contribute to this global problem.
What is climate change?
