Please help with question #9
Il Volcanoes and Igneous Structures Use Google Earth (free download for the PC and Mac, and on many campus computers) to answer the following questions. 7) Go to 34 52'56.23"N, 106°52 24.11"W. This is the center of a 14 basaltic cinder cones. Bassed on the distribution of the cinder cones what type of intrusion underlies the cones? Your answer should be one word. 8) Use the "Fly to" feature of Google Earth to find Ship Rock, New Mexico. Ship rock is an intrusion that used to form the core of a volcano (a volcanic neck). There are linear black features that extend from the neck. These are dikes that formed during the volcanism and intrusion of the neck. How many dikes do you see? 9) Go to 18 9'48.93 "S, 69 8'33.51"W. This is the center of a volcano. You need to zoom out to around 325 mi for the "eye altitude" on Google Earth. What would be the main tectonic process that produced this volcano? One sentence should be enough. 10) What type of volcano is the one from question 9?Explanation / Answer
