Feedback:2 Plate Tectonics Question 5 of 25 4.0/ 4.0 Points The Wilson cycle shows all but which of the following? A. how rocks cycle from one type to another B. how water cycles on the Earth C. how oceans open and close throughout geologic time Feedback:2 Plate Tectonics Question 6 of 25 4.0/ 4.0 Points Oceanic plates are composed of what rock type? A. granite B. quartz C. basalt D. diorite Feedback:2 Plate Tectonics Question 7 of 25 4.0/ 4.0 Points Which type of boundaries involve crust being neither created nor destroyed and shearing motion? A. transform boundaries B. divergent boundaries C. convergent boundaries Feedback:2 Plate Tectonics Question 8 of 25 4.0/ 4.0 Points Ocean-to-continent convergent boundaries can produce all but which of the following? A. volcanoes B. mountains C. new sea-floor Feedback:2 Plate Tectonics Question 9 of 25 4.0/ 4.0 Points Which of the following is the most accurate statement of how the Himalayas were formed? A. They are actually the original elevation of the continent. As the erosion weathered away to give the current surface, it left the mountains behind. B. During the last great flood, sediments were deposited that accumulated and were eventually eroded into mountains. C. As the Indian plate moved into the Eurasian plate, the continents collided and buckled up to form mountains. Feedback:2 Plate Tectonics Question 10 of 25 0.0/ 4.0 Points Which piece of evidence renewed the scientific community's interest in continental drift?
