Types of Rocks
Land forms
Fossils
100
What are small bits of rock and other organic materials called?
Sediment
100
Where do fossil fuels come from?
Oil from fossils
100
What type of rock is spewed from volcanoes?
Igneous rock
100
What land form is between two mountains?
Valley
100
If an animal is eaten and digested, will it form a fossil? Why or why not.
No, there will be nothing left to form a fossil.
200
When sediment chips away from larger rocks, usually from weathering.
Erosion
200
What type of resource are coal and oil? Why?
Non-renewable. Once it runs out, it is gone.
200
What type of rock is formed when pieces of sediment are cemented together?
Sedimentary rock
200
What forms and shapes sand dunes?
Wind
200
What parts of an animal will become the fossil?
The hard parts. i.e. bone, horns, nails
300
What is it called when rocks get placed into a river or ocean after being swept away from erosion?
Deposition
300
What is a negative side effect from burning coal and oil?
Pollution
300
What type of rock is formed after being pushed down towards earth's core and is squeezed and heated?
Metamorphic rock
300
How do beaches change over time?
Sand is washed into the ocean via wave erosion. Sediment is deposited on the beach making it bigger.
300
What must happen for an animal to become a fossil?
It must get buried.
400
In order, what are the two steps when rocks are first gathered into a pile, then squeezed together from pressure to become one rock?
Compaction then cementation.
400
How is coal formed? (3 steps)
Plants die, get buried by sediment, and change from heat and pressure.
400
What causes metamorphic rocks to form?
Heat, pressure, and time
400
What land form is created when a river cuts a "U" shape between large rocks?
Canyon
400
What happens to the soft parts of the animal while becoming a fossil.
They decay which forms oil/ fossil fuels.
500
Name all four stages of the rock cycle.
Erosion, deposition, compaction, cementation.
500
How is oil formed? (3 steps)
Animals die, get buried by sediment, and change from heat and pressure.
500
After a volcano erupts, how do igneous rock form?
The lava cools down.
500
What land form is at the end of a river, also known as the mouth of the river. It forms more branches over time.
Delta
500
What type of fossil is it when an animal leaves behind evidence it was there, such as a footprint.
Trace fossil
