4. Row 1, Col 1 Which type of map projection has both parallel lines of lat. and long.? Mercator

5. 1,2 What is a satellite image made up of? Pixels

6. 1,3 What does a contour line represent? Area of equal elevation

7. 1,4 Name 3 features that you would find on a topographic map of Newton Hills, lakes, rivers, hiking trails, forest areas

8. 2,1 The measurement of distance north and south of the equator Latitude

9. 2,2 What does GPS stand for? Explain how it works and name two problems that can disrupt its communications. Global Positioning System/ Uses a number (at least 3) of satellites that send data to GPS receivers on Earth

10. 2,3 What is a landform ’ s height above sea level called? Elevation

11. 2,4 What are the dark contour lines on a topographic map? (hint: usually every 5 line) Index contours

12. 3,1 Name a landform that has high elevation and a flat surface. Plateau

13. 3,2 Name 3 “false” colors that Landsat satellite use and what they represent. Black-water, red-forests, gray-cities

14. 3,3 How can you tell whether a stream on a map flows into or out of a lake? V-shaped contours would point towards the direction it was flowing from. If the V ’ s point toward the lake, it was flowing from/out the lake

15. 3,4 How do you determine the contour interval on a topographic map? Determine the difference in elevation between 2 dark index contours, then divide that number by number of contour intervals between the dark lines.

16. 4,1 What unit of distance is 1/60 of a degree? Come up to the board and write the following coordinates correctly 47 degrees and 40 minutes north by 0 degrees and 5 minutes east Minute /

17. 4,2 What is the process called that mapmakers use that converts the location of map points to numbers Digitizing

18. 4,3 The difference in elevation between the highest and lowest parts of an area is called its _______ Name a place in the USA has high __________ DAILY DOUBLE Relief

19. 4,4 If the scale on a map is 1:63,360 what does it mean? 1 inch is equal to 63,360 inches or one mile

20. 5,1 Name one country in each of the 4 hemispheres DAILY DOUBLE

21. 5,2 Name 3 ways we rely on satellites Communication, weather forecasting, mapping

22. 5,3 What does the word gradient mean? How could you find the gradient of a area on a topographic map? Slope / Rise/run usually expressed in ft./mile or m/km

23. 5,4 How many degrees of latitude and longitude are there in the northern hemisphere? 90º latitude and 360º of longitude
