What causes igneous rocks to become sedimentary rocks?
The igneous rocks must be broken down
What theory discussed the idea of the tectonic plates moving?
The theory of plate tectonics
True of False:
Scientific knowledge can never be updated?
False
Which layer of the Earth is the densest?
The Core
What type of boundary causes the formation of mountains?
Convergent Plate Boundaries
What type of rock would you expect to find at location C?
Igneous Rock
What was the name of the giant landmass that existed millions of years ago?
Pangea
True or False:
A scientific theory doesn't need to be tested to be proven correct.
False
What are the layers of the Earth in order from the innermost to the top?
1. Inner core
2. Outer Core
3. Mantle
4. Lithosphere
5. Crust
What does this picture depict?
The theory of plate tectonics
How does sedimentary rock turn into igneous rock?
Sedimentary rock is pushed under ground where it is re-melted into igneous rock.
What is this type of boundary called?
Divergent Plate Boundary
True or False:
A scientific paper needs to be reviewed and proven correct before it can be published.
True
What is occurring at the arrows in the mantle of the Earth?
Convection Currents
What are convection currents made of?
Magma
What is needed for igneous rock to turn into metamorphic rock?
High heat and pressure under ground
When two tectonic plates move quickly past one another and cause this type of natural phenomenon?
What is needed to change scientific knowledge that was previously proven correct?
New evidence
What causes the movement of the tectonic plates?
Movement of convection currents within the mantle.
What type of rock would you find at location A?
Metamorphic Rock
What type of rock would you find at location B?
Sedimentary Rock
What type of boundary is located in California?
Transform Plate boundary
How do scientists know that the mid-Atlantic ridge is spreading apart?
Because the older rocks are found farther away from the middle.
What is occuring at the middle between the two currents?
The currents are running into each other and will cause a plate to rise up.
Why would the theory of plate tectonics be reviewed and updated?
Because new evidence was uncovered and it needed to be updated.
