What was the name of the supercontinent that started breaking apart about 175 million years ago?
Pangaea
100
The large plates move across the surface of the Earth by what process?
convection
100
Name the three plate boundaries.
Convergent, Divergent, Transform
100
True or False When two continental crusts converge, they collide and push against each other.
True

Explain why the carrots floated in the Carrot Density Lab?
The saltier the water became the denser it was, making the water more dense than the carrots.
200
Which of the following scientists proposed the Theory of Continental Drift?
Wegener
200
The San Andreas Fault in California is known as an active earthquake area. What type of boundary is it?
Transform Boundary
200
The Theory of Plate Tectonics suggests that ____ currents pushed plates in Earth’s mantle.
convection
200
The scientist who proposed the theory that seafloor spreading causes tectonic plates to move.
Hess or Harry Hess
200
If I wanted to conduct an experiment to show convection currents, what could I do?
You could do the bottle experiment with hot water and cold water and food coloring to show how hot water rises and sinks.
300
Originally the Theory of Continental Drift was not well received by other scientists. Why was this?
The scientists didn't know the force responsible for moving the continents.
300
Find the Nazca and the South American Plate. This is an example of two plates subducting. What features are likely found here?
volcanoes
300
How did the theory of plate tectonics support the theory of continental drift?
It explained how the continents moved.
300
Below is a picture of sea-floor spreading. How are the ocean crusts moving?
dividing, separating, moving apart
300
What happens with temperature when comparing inland and coastal cities?
Temperature in coastal cities doesn't change very much, but with inland cities like Wichita, KS the temperatures fluctuate from very high to very low.
400
If different rocks are found on each continent with no relationship between them would this be an example to support the Theory of Continental Drift?
No, it would not.
400
The Indian Plate converges with the Eurasian Plate. When two continental plates converge what crustal features are expected to form?
folded mountains
400
Which of the following is a transform boundary?
A
400
When an oceanic crust meets a continental crust, what occurs?
The oceanic crust moves under the continental crust resulting in volcanoes.
400
When two oceanic plate boundaries meet, what crustal feature forms?
volcanic island arc
500
What four pieces of evidence could be needed to support the Theory of Continental Drift?
fossil evidence, continental fit, glacial evidence, landforms and rock layers
500
Which of the diagrams shows a divergent plate boundary?
B
500
Which plates will subduct?
denser or older
500
True or False All converging boundaries result in a subduction zone.
False

Which of these terms means “scratches in rocks caused by glaciers”?
striations
