Go to the following Geotours Folder in Google Earth; 2. Exploring Geology Using Google Earth rightarrow Geotour Worksheets rightarrow Geologic Structures. Check and double-click the polygon 'Flatiron' in the Problem 1 folder within the 1. Geologic Structures worksheet folder to fly to the northeaster flank of the Wind River Mountain range in Wyoming. You may recall from the sedimentary rock worksheet that tilted sedimentary rocks pointed or rounded edge pointing in the direction opposite of the tile (geoscientists thought that this geometry resembled the flat bottom of a laundry iron, hence the name). In this view, the polygon outlines one of the many flatirons that border the uplift (flatirons are common in folded/tilted sedimentary strata). To make it easier to see, you might consider temporarily increasing the vertical exaggeration to 2 in Google Earth. (It is recommended you continue this from Question 2) Note the length of the dip line in meters (or the same units that your elevations are in) and hover over the point of place mark Problem 1b dip to determine its elevation. What is the approximate dip angle (00 degree - 90 degree)? To determine the amount of dip, use the following formula: dip - tan^-1 ((elevation difference between place mark problem lb-dip & strike line) + length of the dip line). Choose one: 05 degree 12 degree 19 degree a. 26 degree b. 31 degree c. 37 degree d. 43 degree e. 48 degree
