Question

Go to the following Geotours Folder in Google Earth: 2. Exploring Geology Using Google Earth ? Geotour Worksheets ? K. Earth History. Check and double-click the “Paleogeographic Model” folder in the "Global Paleogeographic Model" folder within the K. Earth History worksheet folder and make the entire folder semi-transparent. Turn on the latitude and longitude lines (View ? Grid) and Borders and Labels in the Layers panel. Now, play the time animation through several times and rotate the globe to watch the animation from different perspectives. You can manually play the animation by grabbing the right part of the time slider and moving it, or you can toggle the animation on/off automatically by clicking the right-most clock icon in the historical animation box (upper left corner of the Google Earth viewer). Leave the Paleogeographic Maps checked to answer the following questions. Check and double-click placemark Problem 1d. Watch the landmass in the center of the view as the animation goes from Problem 1c to 1d (do this a couple of times to study it carefully). This landmass will become North America. During this time period, it is growing by accreting terranes to its margins. What kind of plate tectonic boundary is likely responsible for these series of mountain building events?

convergent

transform

divergent

Explanation / Answer

This landmass will become North America. During this time period, it is growing by accreting terranes to its margins. What kind of plate tectonic boundary is likely responsible for these series of mountain building events?

(a) convergent

This is convergent plate boundary i.e, when two tectonic plates are moving towards each other results in collision and smack into one another and lift up each other results in mountain ranges.
