Describe both the mechanics and features of a convergent plate boundary that produces andesite volcanoes.

Test #1 Short Answer This is the short answer portion of test #1. ================================================= BOOK: Earth 11th edition An Introduction to Physical Geology ================================================= It is multiple entry, untimed, and open book. Please be aware of the plagiarism policy for the course and college, make sure you paraphrase/explain things in your own words. If you submit more than one time, I’ll grade the last submission. ———————— Write your answers below, 4 points each-20 points total. You have unlimited time, so I expect a lucid and complete but not necessarily long answer. Be aware of the course and colleges plagiarism policy. 1) How did Dr. Alfred Wegener use both fossils AND present-day plants and animals to support Continental Drift Theory? Clearly explain the lines of evidence and logic he used to support his conclusions. 2) The Aleutian and Hawaiian Islands form from completely different processes related to Plate Tectonics. Using Plate Tectonic theory and correct technical terms, explain how they form. 3) Describe both the mechanics and features of a convergent plate boundary that produces andesite volcanoes. Be sure to use terms like continental and oceanic crust, the different rock types-granite basalt etc, the subduction zone and trench, and the force that causes the boundary. 4) Describe the Toba Eruption, what is the geologic setting, how big was it, where and when did it occur? Discuss the duration and changes to climate and how it affected the human population at the time. 5) Describe how and what the properties of P+S waves tell us about the interior of the earth. How do these data help explain a mechanism for plate tectonics?
