7. How do you explain a plate boundary to cause volcanic activity A. When two plates slide past one another. B. When the plates move apart, and magma leaks up C. When two continental plates collide and push rock upward D. When the denser oceanic crust slides underneath the continental
8. What do you expect to find at a mid A. Relatively young rocks C. Thick accumulation of sediment - ocean ridge? B. Reverse fault D. Very ancient rocks
9. Which of the following is NOT a result of divergence of plates? A. Earthquake B. Mid- oceanic ridge C. Rift valley formation D. Volcano 10. Right in the middle of an island, you can find a rift valley. What type of plate boundary exists on that island? A. Convergent B. Divergent C. Normal D. Transform fault
11. How do you explain ridge formation? A. When two plates slide past one another. B. When one plate moves underneath another. C. When two continental plates collide called a convergent boundary. D. The plates move apart, and magma leaks up and hardens leaving behind a ridge valley
12. What is a possible result of plates moving along a transform - fault boundary? A. Convection B. Earthquakes C. Oceans D. Seafloor spreading
13. Which of the following is the best exanıple of transform plate boundary? A. Himalayan Mountains B. Marianas Trench C Mid Atlantic Ridge D. San Andreas Fault
14. What happens at the transform - fault plate boundary? A Two plates slip horizontally past each other. B. Two plates are subducted beneath each other. C. Two plates move in opposite directions toward each other. D. Two plates move in opposite directions away from each other.
15. Plate A and B shows a divergent boundary. If plate Cis adjacent to both plat- and does not show ant relative motion, what type of plate boundary is prese between A and C? A. Convergent B. Divergent C. Normal fault D. Transform fault​
