After you have completed this worksheet, answer the following quiz questions. Do not attempt the quiz until you have completed the Lab. This quiz is made up of multiple choice questions for a total of 20 points possible on the quiz. You must complete this quiz after you start it. You cannot save the quiz and return to complete it later. You will have 30 minutes to complete the quiz. If you miss a question, you will be able to see the question you missed and the answer you submitted. You will not see the correct answer. Looking up the correct answer makes quizzes a valuable study tool for students. You will have 2 attempts available, but different questions on the same topics may appear on each attempt. The highest score will count toward your grade. A017) Transform Boundary - Mid-Atlantic Ridge. Which direction are the placemarks for Problem 17-north and Problem 17-south moving, respectively? Think about the process of rifting at the mid-ocean ridges.

Assume that the earthquake depths define the Wadati-Benioff zone for the subducting slab. Compare your answers to Problems 9-12 and choose the statement that best describes your observations. A018) Transform Boundary - San Andreas Fault, CA. Check and double-click the Problem 18 folder to see a drywash (blue line) that was offset by the San Andreas Fault. What type of transform fault is the San Andreas Fault? Imagine walking toward the fault zone along the offset feature, and think about which direction you would look to see the other piece of the offset feature. A016) Transform Boundary - Mid-Atlantic Ridge. Which direction are the placemarks for Problem 16-north and Problem 16-south moving, respectively? Think about the process of rifting at the mid-ocean ridges.

What is the approximate age of the bend in the Hawaiian Island–Emperor Seamount hot-spot chain ( should you use the age of the volcanic features or the age of the seafloor)? A019) Check the box next to the Seafloor Age Map folder to view the ages of the oceanic crust around the world. Note that you can select the folder and use the transparency slider at the bottom of the Places panel to make the items in this folder semi-transparent. Turn on the Tectonic Plates folder (divergent = red, convergent = green, and transform = light blue). Also, in the Layers panel, turn on Borders and Labels and Gallery > Volcanoes . Oceanic Hot Spots - Hawaiian Island–Emperor Seamount Chain. Make the Seafloor Age Map semi-transparent, and turn on the Hawaiian Island–Emperor Seamount Chain folder to show their age of formation in millions of years (Ma). Use the Ruler tool to measure the distance between Midway Atoll and Kilauea (cm; Problem 19 placemarks) and calculate the average velocity of the Pacific Plate in cm per year.
