Plate Boundaries and Rock Cycle (3a, 3b, 3c)
1. What does the Theory of Plate Tectonics help scientists explain?___________________________________________
2. When plates move, they can form 3 types of plate boundaries.
List the boundaries: 1._________________, 2._________________, 3.______________
3. The uppermost mantle of the Earth, along with the overlying crust, behave as a strong, rigid layer. What is the name of this layer
that makes up tectonic plates? _______________________
4. What kind of plate boundary occurs where two plates grind past each other without destroying or producing lithosphere?_______
5. Deep ocean trenches are associated with oceanic plates that are forced down into the mantle beneath a second plate. What is the
name of this convergent boundary deep ocean trenches are associated with? _________________________
6. What type of plate boundary is shown in the figure to the right?____________________
7. What type of boundary is the San Andreas fault?_________________________
8. Volcanic mountain ranges form by volcanic activity caused by the subduction of oceanic lithosphere
beneath a continent. Which type of boundary will form volcanic mountain
ranges?________________________
9. At a divergent boundary, when spreading centers develop within a continent, the landmass may
split into two or more smaller segments. They can develop on the seafloor or on land. What forms?____________
10. Paleomagnetism is the natural remnant magnetism in rock bodies and provides evidence of tectonic plates. The discovery of
strips of alternating polarity, which lie as mirror images across the ocean ridges, is among the strongest evidence of____________.
11. How does the age of seafloor sediments change with increasing distance from the ocean ridge?_________________________
12. What happens when two continental plates collide?______________________________________
13. What naturally formed solid is usually made up of one or more types of minerals?____________________
14. What does the texture of a rock—that is, the size of its mineral crystals—depend on?_______________________
15. What type of rock that forms when molten rock cools and crystalizes?_______________________________
16. What type of rock forms when pieces of older rocks and loose material are cemented together?__________________________
17. What type of rock forms when heat and pressure cause older rock to change into new kinds of rock?_______________________
18. Which of the following is NOT one of the three types of rock?_________________________
19. How are Igneous rock, Sedimentary Rock, and Metamorphic Rock classified?_____________________________
20. A student finds a rock containing large fragments of gravel and fossils cemented together. What type of rock could this
be?_____________________
