1. Trivia
Volcanoes

2. Question 1
Volcanoes mostly occur along the “Ring of Fire”. This is because
The mass of the water in the ocean forces magma to rise
These areas are low in population
Earth is hotter in these regions
Plate boundaries are located in these areas.

3. Question 2
Earthquakes often occur before and during an eruption because
There is no reason why
Rocks that fall from the volcano shake the ground
Lava flowing out of the vent shakes the rocks of the volcano
Magma coming up under the volcano’s vent moves the rocks of the volcano.

4. Question 3
Volcanoes and earthquakes both often occur in similar areas because
Magma is formed where there are earthquakes
Both are caused by interacting tectonic plates
The outer core causes both
Earthquakes cause magma to come up through volcanoes

5. Question 4
Volcanoes occur when one plate is pushed under another plate. This movement is called
Shearing
Divergence
Convection
subduction

6. Trivia
Earthquakes

7. Question 1 Compression Tension Shearing compaction
What kind of stress is illustrated below?
Compression
Tension
Shearing
compaction

8. Question 2 Compression Tension Shearing compaction
What kind of stress is illustrated below?
Compression
Tension
Shearing
compaction

9. Question 3 Volcano River Mountain valley
With the type of stress shown in this diagram, the end result would most likely be?
Volcano
River
Mountain
valley

10. Question 4
This is a picture of a transform fault on Mars. What kind of stress is affecting this area?
Compaction
Shearing
Compression
tension

11. Question 5
This is a picture of an African rift valley. It was formed by what kind of stress?
Compression
Tension
Shearing
compaction

12. Question 6
Faults occur because stress builds up in rock. This stress causes the rock to break suddenly releasing energy. When this happens you have a
Volcano
Earthquake
Hurricane
mudflow

13. Question 7
There is stored energy in lithospheric plates along faults. When stored energy suddenly releases:
Earthquakes almost never occur
Earthquakes never occur
Earthquakes are possible
An earthquake is occurring.

14. Question 8
The reason that volcanoes and earthquakes occur in similar areas is:
Earthquakes cause magma to be released
Magma is only formed where there are earthquakes
The inner core causes both
Both are caused by the interaction of tectonic plates.

15. Question 9
Convergent plate boundaries are caused by which type of stress?
Tension
Compression
Erosion
Shearing.

16. Question 10
Divergent Plate boundaries are formed due to what type of stress?
Shearing
Tension
Weathering
compression

17. Trivia
Plate Tectonics

18. Question 1
You can find some of the same fossils on the coast of South America that you can find in Antarctica. How can this be explained?
The species traveled across the ocean.
The species just grew on each continent on its own.
The continents were once together, but have now spread apart.
There is no accepted explanation.

19. Question 2
If two plate boundaries collide and they are made of continental crust, what feature will be formed?
Subduction zone
Mountain range
Rift valley
ocean

20. Question 3 The Theory of Plate Tectonics explains: Earth’s composition
How sedimentary rock is formed.
The movement of the Earth’s surface
Why plants grow in certain climates.

21. Question 4
The Atlantic Ocean gets bigger and bigger with time. This is happening because of:
A convergent plate boundary in the middle of the ocean.
Volcanoes and Earthquakes
The spreading of the oceanic plates
Increasing amounts of rain.

22. Question 5
When oceanic crusts collide, one plate subducts under another plate forming a
mid-ocean ridge
Divergent plate boundary
Trench
A transform plate boundary.

23. Question 6
Rift valleys are an example of
Convergent plate boundaries
Transform plate boundaries
Divergent plate boundaries

24. Question 7
Which of the following is an example of evidence that Alfred Wegener used to support his Theory of Continental Drift?
Cavemen left drawings indicating that the continents were together.
Photographs of the mid-ocean ridge.
Fossils of the same species found on separate continents.

25. Question 8 Subduction zones are a feature of
Convergent plate boundaries
Divergent plate boundaries
Normal Faults
Strike-Slip Faults
