Sedimentary
Fossil Fuels
Fossils
100
This is when sediment is carried from one place to another.
Erosion
100
What are all 5 steps for making sedimentary rock?
Weather, Erosion, Deposition, Compaction, and Cementation
100
Why are fossil fuels non-renewable?
because they take millions of years to make.
100
Whats the first step of fossil formation?
Dead organism.
200
This is where rock is broken into sediments.
Weathering
200
What is the definition for compaction?
The pressure of the layers of sediment compacting together.
200
What is the difference between oil found in the ground and peanut oil?
One is non-renewable and the other is renewable.
200
I laid a piece of leaf on the bottom of a pot. What would my next step be to MODEL how a fossil is formed.
Adding a layer of something (sand etc.)
300
Sediment is moved at different speeds. What would the slowest form of movement be from?
Think wind, water, ice.
glaciers
300
What is the definition of cementation.
Water is pushed out of the sediment leaving behind minerals that act as glue.
300
What is oil and natural gas made from? How to do you get natural gas instead of oil?
Marine animals and more heat and pressure.
300
Does everything that dies become a fossil? Why?
No, it has to be the perfect conditions. Organic matter has to be covered by sediment immediately by sediments and must decay inside the rock.
400
Without deposition we would not have sedimentary rock. Why is that?
Deposition is the start of forming the different layers that will later cause pressure that form our sedimentary rock.
400
What are two things that we find in sedimentary rock?
Fossil fuels and fossils.
400
How is coal different from oil and natural gas?
Dead plants from swamps.
400
What organism lived in the oldest sedimentary rock?
Trilobites
500
Weathering, Erosion, and Deposition are important for sedimentary rock. Why might some students forget about them when talking about the formation of sedimentary rock?
Varying answers.
500
Sedimentary rocks are formed in a cycle. Explain the cycle.
Sedimentary rock is...
500
What is similar between all the fossil fuels?
heat and pressure
500
What does this model explain to us?
That throughout the millions of years these different layers of sedimentary rock were formed the locations environment changed.
