CHAPTER 7 REVIEW QUESTIONS:
1. Who is credited with the development of the continental drift hypothesis?
2. What was probably the first evidence that led some to suspect the continents were once connected?
3. What was Pangaea?
4. List the evidence that Wegener gathered to substantiate the continental drift hypothesis.
5. Early in this century, what was the prevailing view of how land animals migrated across vast expanses of ocean?
6. What are the three major types of plate boundaries? Describe the relative plate motion at each of these boundaries.
7. What is seafloor spreading? Where is active seafloor spreading occurring today?
8. What is a subduction zone? With what type of plate boundary is it associated?
9. Briefly describe how the Himalaya Mountains formed.
10. Some predict that California will sink into the ocean. Is this idea consistent with the theory of plate tectonics?
11. How do hot spots and the plate tectonics theory account for the fact that the Hawaiian Islands vary in age.
12. What type of plate boundary is associated with: Himalayas, Aleutian Islands, Red Sea, Andes Mountains, San Andreas Fault, Iceland, Japan, Mount St. Helens?

7.) Compare and contrast the three main types of volcanoes.
8.) Name one example of each of the three types of volcanoes.
9.) What is Ship Rock, New Mexico, and how did it form?
CHAPTER 10 REVIEW QUESTIONS
1.) What is rock deformation?
2.) List three factors that determine how rocks will behave when exposed to stresses that exceed their strength. Briefly explain the role of each.
3.) Distinguish between anticlines and synclines, domes, and basins, anticlines, and domes.
4.) Contrast the movements that occur along normal and reverse faults. What type of force is indicated by each fault?
5.) Describe a horst and a graben. Explain how a graben valley forms, and name one.
6.) What type of faults are associated with fault-block mountains?
7.) The San Andreas Fault is an excellent example of a _______________ fault.
8.) How are joints different from faults?
9.) The formation of mountainous topography at a volcanic island arc, such as Japan, is considered just one phase in the development of a major mountain belt. Explain
10.) How does the plate tectonics theory help explain the existence of fossil marine life in rocks atop mountains formed by continental collisions?
11.) Briefly describe the major differences between the evolution of the Appalachian Mountains and the North American Cordillera.
12.) What is the ring of fire?
13.) The Hawaiian Islands and Yellowstone Park are thought to be associated with which of the three zones of volcanism?
Explanation / Answer
Chapter 7 review questions:-
1. Alfred wegner
2.coast of africa and america fits together
3.pangea is a all continent joined together, called supercontinent
4.rock ditribution, mountain ranges,connection and fit between different continents
5. there is constant change of place between ocean and land masses
6 divergent boundary in which plate oves apart from each othe, convergent in which plate move toward each other, transform where two plates chaneg position with eah other
7.occur at mid ocean range, new crust is fomed by volcanic eruption
8 zone of high earthquake,volcanism. Area where subducting plate overriding plate
9 by collision of plates at midoceanic range
10 no it is false, the sanandreas fault system will cross california from salton sea
11 sometime plate techtonics can cause volcanic eruption and causes hot spot to form this is the way hawai island was form but we should understand that these can be different time zone things . volcanic eruption occur after plat movements, hawai islands is understood to island formed from volcanic eruptions. so the time period changes
12 convergent, convergent,convergent , convergent ,san andreas-transform, iceland-divergent and rest all are convergent.
