Diameter: ______________ km Center_Long: _______________ ° Center_Lat: _______________ ° Question 1 options: Skip Toolbars More Insert actions. Show All Components Save Question 2 (2 points) Select the tool from the upper right side of the screen. A small window will appear with three icons. The left icon, "Point-Coordinates" will return the location of the cursor when we click on the map. • Select "Point-Coordinates", move the cursor to the thumbtack and click. The X and Y coordinates will appear in the window. Record the values below. • Be sure to read the IMPORTANT NOTE in the lab textbook! 2.

Show All Components Save Question 3 (1 point) In the "Measure" Window, click on the center icon, "Line-Distance", to measure distances and sizes on the screen. (Consult the lab textbook for the entire description of steps to to take.) • Move the cursor to the right side of the outer ring so that the black line is horizontal across the corona. Double-click to end the line. The length of the line will be displayed in the "Measure" window. Change the length value to kilometers. • Be sure to read the NOTE in the lab textbook. 3. Using the "Line-Distance", measure the diameter in km of the inner ring of Hervor Corona. Total Length of inner ring: ____________________ km Question 3 options: Skip Toolbars More Insert actions. Show All Components Save Question 4 (2 points) An example of a Radial-Concentric corona is Selu Corona. The radial concentric type has intense fracturing that radiates from the center of the corona along with the typical circular fracture pattern. • Click on to return to view the entire surface. Use the and the tool to find the X and Y Coordinates. Selu Corona: X Coordinate: ____________ Y Coordinate: ____________ Question 4 options: Skip Toolbars More Insert actions. Show All Components Save Question 5 (1 point) Another type of corona is the Concentric-Double corona. These are similar to the basic type of corona, Concentric, but they have two distinct annular ridges and/or moats instead of one. An example of a Concentric-Double Corona can be found at X = -83.9 and Y = -29.9. • Enter these coordinates in the window and click . Keep zooming in until the zoom level is 8.
