What did the twizzler represent in our study of the earth's layers
What is the core
300
This is the process that breaks rocks into smaller pieces.
What is erosion (and weathering)
300
Metamorphic rocks are formed by...
What is heat and pressure
300
True or False: Scientists know about the layers of the earth because they have dug to the core and explored
What is False
300
How do convergent plate boundaries move?
toward each other
300
Explain how an oreo can represent plate tectonics
top = lithosphere, middle = asthenosphere, and bottom = lower mantle
400
Tiny pieces of rock can also be called this
What is sediments
400
Igneous rocks are formed by...
What is magma cooling
400
Describe the lithosphere
What is the uppermost part of the mantle and crust. This is the part that moves from plate tectonics.
400
How do divergent plate boundaries move?
away from each other

If you had to make a demonstration of the earth's layers out of food, what could you use (besides what you have already used with Ms. Martin:)
Answers may vary
500
Explain an example of a rock going through the rock cycle.
Sample answer: The rock starts in the earth's interior and turns to magma and cools to become igneous. Weathering and erosion cause the rock to turn into tiny sediments. The sediments undergo lithification and it becomes sedimentary.
500
Give an example of a specific igneous, metamorphic or sedimentary rock
Sample answer: obsidian = igneous
500
Describe the asthenosphere
The asthenosphere is within the mantle. It is hot and can allow the lithosphere to move.
500
Describe "sliding plate over asthenosphere"
Plates moving up over each other
