Question 3. (1pts) The 49th parallel north forms a portion of the border between which two countries?
Question 4. (10pts) Identify longitudes of the following cities. Hints: to search for a city, type the city name into the Search Box and click Search. Notes: each correct answer is worth 1 point. City names Longitudes
Cabo San Lucas, Mexico
Cincinnati, Ohio
Niamey, Niger
Hue, Vietnam
Paris, France
Cairo, Egypt
Kathmandu, India
Sendai, Japan
Manila, Philippines
London, England
Question 5. (6pts) What are the six U.S. states through which the 100th meridian in the Western Hemisphere passes? Hints: from the Layers panel, turn on the Borders and Labels layer to identify the states.
S5. From the menu bar, choose File ? Open…
S6. In the Open dialog, navigate and select the KMZ file downloaded above, and click Open
You should now see the Earth rotating and several places added to the Places panel.

S7. From the Places panel, select and double click the Equatorial Latitude place folder
You should now see placemarks A and B on the screen. The angular distance from placemark A to placemark B is 10o of latitude.
S8. From the tool bar, select the Show Ruler tool
S9. In the Ruler dialog, change the unit to Kilometers
The Ruler tool is used to measure distance between any two points in Google Earth. Distances may be presented without accounting for terrain (i.e. Map Length) or with accounting for terrain (i.e. Ground Length). In other words, map lengths are crow-fly distances whereas ground lengths are turtle-crawl distances.
Question 6. (1pt) Use the Ruler tool, determine the map distance (in Km) between placemark A and placemark B.
Question 7. (1pt) What is the map distance (in Km) between placemark C and placemark D under the Polar Latitude place folder?
Question 8. (5pts) From the answers above, what is your conclusion about the length of 10o of latitude at the equator and the length of 10o of latitude at the pole?
Question 9. (6pts) What are the map distances (in Km) of the following 10o longitudes? Note: each correct answer is worth 1 point. Please present you answers in a table as shown below. Longitudes Distances (in Km)
Equatorial longitude
Tropical longitude
GEO 108 – Physical Geography
Page 5
Mid-latitude longitude
Sub-arctic longitude
Arctic longitude
Polar longitude
Question 10. (5pts) Why does the linear distance of 10o of longitude decrease as you travel from the equator to the pole?
S10. From the Places panel, turn on (check) and double click the Latitudinal Zones placemark to make the overlay visible.
Latitudinal zones are geographic regions running east-west. These zones are associated with natural environments that differ dramatically from the equator to the poles due to the differences in the amount of solar energy received, which varies by latitudes. It should be noted that the boundaries of these zones are rather flexible than rigid. Thus, they should be considered as transition areas rather than a single line.
Question 11. (10pts) What latitudinal zones are the following locations in? Note: each correct answer is worth 1 point. Please present you answers in a table as shown below. Longitudes Zones
Vancouver, B.C., Canada
Dunedin, New Zealand
Phu Quoc, Vietnam
Moosejaw, Saskatchewan
Miami, Florida
Reykjav’k, Iceland
Longyearbyen, Svalbard

Part B: Map Scale
Map scales represent the ratios between distances on maps and those in real world. For example, a map scale of 1:24,000 means that a distance of 1 cm measured on a map is actually 24,000 cm in reality. Map scales may be fixed and static in printed maps. However, map scales may be dynamic in digital maps presented on computer screens. In Google Earth, the Zoom tool allows its users to change the map scale and thus the map details. Indeed the larger the scale is, the more details you can see. Map scale may be viewed as a scale legend at the bottom of the Google Earth interface.
S11. From the menu bar, select View ? Scale Legend and then zoom in the globe to see the scale legend appearing at the lower left corner
S12. From the Places panel, turn on and double click the Map Scale View 1. Then, use a ruler to measure the distance from Placemark 1 to Placemark 2 by placing your ruler against the screen.
Question 12. (1pt) What is the distance in cm?
S13. Use the Google Ruler tool to measure the same distance (i.e. from Placemark 1 to Placemark 2). Hints: to make it easy, set the units of the Google Ruler tool to cm as well.
Question 13. (1pt) What is the distance in cm?
Note that the distance provided by your ruler is the map distance whereas the distance provided by the Google Ruler tool is the real distance (or ground distance). Therefore, the map scale of this view (i.e. View 1) is calculated by taking the ratio between the distance provided by your ruler and the distance provided by Google Earth Ruler tool.
Question 14. (1pt) What is the map scale of View 1?
S14. From the Places panel, turn on and double click the Map Scale View 2
Question 15. (1pt) What is the map scale of View 2?
Part C: GIS
Google Earth is a geographic information system (GIS) with an easy-to-use interface. Therefore, Google Earth inherits the powers of GIS. As a result, Google Earth is able to answer the questions of what is
GEO 108 – Physical Geography
Page 7
where based on both locational data and attribute data demonstrated as layers. Google Earth has many layers presented in the Layers panel. Take a few minutes to explore these layers.
Question 16. (10pts) In 3 sentences, let me know which is your most interesting layer and why?
Question 17. (10pts) If you have to choose 3 layers to answer a geographic question, what will they be and how will you use them? For example, I would use the Roads, Places, and Photos layers to identify a hotel and the route to get there.
