In this box there is a tab called Fly to which acts as a search bar that will take you wherever you wish to go to in the world. - Under the Fly to box is the Places box. Each check box here represents a layer that can be turned on or off by clicking in the box. If you are loading a map or a kmz file into Google Earth it will show up here. - The last box is the Layers box. This box has different basic layers, for example: Roads, Traffic, and Weather. -Make sure the Terrain layer is turned on - Tool Bar across the top of the screen - This toolbar has many different buttons, simply scroll over them with your mouse to find out what they are. - One of the useful tools on the toolbar is the Ruler which measures distances along the ground. -The Google Earth Options has settings that you can change if desired. To get there go Tools>Options>3D View -Show Lat/Long>chose Decimal Degrees -Show Elevation> chose Meters, Kilometers -Terrain Quality> the range is between is less than the actual elevation, and 3 is very exaggerated. You can change this to whatever suits your fancy.

3 Name: Part 3: Exercises 1. How much have you used Google Earth? a. Never b. A few times c. Several times a semester d. Almost every week 2. Fly to JMU, then find the HHS / ISAT building (east campus). On the Google Earth image, what is located where the East Campus Library should be located? So, how old do you think the Google Earth image is? Fly to the JMU Quad. What else is out of date on the Google Earth image? 3. What is your hometown? What are the latitude and longitude of your hometown? How many kilometers is it from your hometown to JMU, in a straight line? 4. How tall is the peak of Massanutten Mtn. at the ski area? To see it better you can exaggerate its elevation by going into Tools>Options>3D View>Terrain Quality>Elevation Exaggerate=3. 5. What is the length of the Chesapeake Bay Bridge-Tunnel? (kilometers) 6. Find the latitude, longitude and elevation of the Matterhorn (in the Alps).

4 7. Fly to these latitude and longitude coordinates N, E. Once you are there push the up arrow on the eye controller until your viewing angle is parallel with the ground, then rotate your view. What feature are you looking at? What is its elevation? 8. Look at the region around the Himalayan mountain of K2; do you notice any evidence of glacial activity? Explain. 9.

What is the difference in elevation between the Colorado River and the rim of the Grand Canyon (the plateau) above the river? 11. Fly to , What kind of surface process has happened here in regards to the nearby river? 12. Fly to , Explore this area by zooming in and out and tilting the view.
