The Rock Cycle
3
100
In this stage of a volcano, the volcano is sleeping and may erupt again.
What is a dormant volcano?
100
A rock is made up of these mixed with other materials.
What iare minerals?
100
How an igneous rock become a metamorphic rock.
What is through heat and pressure?
100
These are the three stages of a volcano.
What are extinct, dormant, and active?
200
This the stage of a volcano that is currently erupting.
What is an active volcano?
200
This type of rock forms from cooled magma or lava.
What are igneous rocks?
200
This is how a sedimentary rock starts to become an igneous rock.
What is through erosion?
200
These are the three types of rocks.
What are igneous, sedimentary, and metamorphic?
300
This type of volcano is a combination of a shield and cinder-cone.
What is a composite volcano?
300
This type of rock forms when other rocks erode and deposit.
What is sedimentary rock?
300
This is how magma and lava turns into igneous rocks.
What is through volcanic activity?
300
These are three types of volcanoes.
What are composite, cinder-cone, and shield?
400
This is the smallest lava fragment produced by an explosive eruption.
What is volcanic ash.
400
This type of rock forms under heat and pressure.
What is metamorphic rock?
400
This is a series of processes that slowly changes rock from one type to another.
What is the rock cycle?
400
These are three ways any type of rock can turn into another type of rock.
What are heat and pressure, erosion, and volcanic activity?
500
This type of volcanic eruption produces ash, cinder, bombs, and gases from a volcano.
What is pyroclastic flow?
500
This is the strongest rock and ranks 10 on the Moh's hardness scale.
What is a diamond?
500
The movements of these begins the rock cycle by helping to form magma, the source of igneous rock.
What are plates?
500
These are the three layers of the earth. This layer is where the heat that changes a rock into a metamorphic rock comes from.
What are the mantle, crust, and core? What is the mantle?
