Wild Card 100

• Any circle that runs east and west around Earth,
  and that is paralell to the equator.
• Answer- A line of latitude.
• Return to board

4
Wild Card 300

• On a topographic map, elevation is shown by means
  of.
• Answer- Contour lines.
• Return to board

5
Wild Card 400

• What is wrong with the following location 135º
  N, 93º E ?
• Answer- The maximum reading for a latitude (North
  or South) is 90º
• Return to board

6
Wild Card 500

• As you move from point A to point B in the
  Northern Hemisphere, the length of a degree of
  longitude progressively decreases. In which
  direction are you moving?
• Answer- North (moving S to N), or South (moving N
  to S)
• Return to board

7
Potpurri 100

• What is the latitude of the North Pole?
• Answer- 90º N.
• Return to board

8
Potpurri 200

• What is the angular distance, measured in
  degrees, east or west of the Prime meridian?
• Answer- Longitude
• Return to board

9
Potpurri 300

• What is the maximum number of 1 degree latitude
  lines that can be drawn on a globe?
• Answer- 90 lines of 1 degree each (LATITUDE !!)
• Return to board

10
Potpurri 400

• Choose one Lines of Longitude describe
  position..(east/west of prime meridian, or
  north/south of equator)
• Answer- East/West of Prime Meridian
• Return to board

11
Potpurri 500

• Approximately how many degrees wide are the time
  zones on a globe. Are these latitude or longitude
  lines.
• Answer- Approximately 15º longitude. The lines
  roughly correspond to meridians (longitude),
  except for changes made so that cities are not
  split in half.
• Return to board

12
Interpreting Maps 100

• On a topographic map, contour lines that are
  closer together indicate.
• Answer- A steeper slope.
• Return to board

13
Interpreting maps 200

• What part of a road map would you use in order to
  measure the distance from your current location
  to your destination?
• Answer- The map scale !!! (you would need a ruler
  or measuring device)
• Return to board

14
Interpreting maps 300

• A topographic map shows 2 hiking trails. Along
  trail A the contour lines are widely spaced.
  Along trail B, contour lines are almost touching.
  Which path would likely be easier to follow? Why
  ?
• Answer- Trail A (has a gentler slope)
• Return to board

15
Interpreting maps 500

• Where on Earth would longitude lines separated by
  1 degree represent the largest distance?
• Answer- Exactly on the Equator 1 degree of
  longitude111 km. Elsewhere is a smaller
  distance.
• Return to board

16
Interpreting maps 400

• You observe a topographic map on which the
  contour interval is 100 meters. In general, what
  type of terrain is probably represented on the
  map?
• Answer- Hilly terrain ! (if it were relatively
  flat terrain, the contour interval would be much
  smaller, such as a few feet only)
• Return to board

17
Mapping skills 100

• If 1 kilometer is equal to 1 centimeter on a map,
  what is the distance between two cities that are
  7.5 cm apart on the same map?
• Answer- The distance is 7.5 kilometers
• (7.5 cm)(1 km)/1 cm 7.5 km
• Return to board

18
Mapping skills 200

•  If you are exactly on the corner of the Equator
  line (latitude) and the Prime Meridian, and you
  travel to a location that is 90º East from the
  prime meridian, what distance would you have
  travelled?
• Answer- 9,990 km (nine thousand, nine hundred and
  ninety) 90º x 111km9,990 km
• Return to board

19
Mapping skills 400

• What does the legend of a map contain that is not
  contained in either the scale or the contour
  interval?
• Answer- The symbols used in he map to represent
  various features (rivers, roads, peaks, etc)
• Return to board

20
Mapping skills 500

• What kind of instrument would be needed to map
  the surface of the bottom of the ocean?
• Answer- An instrument that uses sonar
  (echo-sound), such as the Sea Beam
• Return to board

21
Mapping skills 300

• What 3 items does GPS technology require in order
  to provide you with a position that you can use
  to determine your location on a printed map
• Answer- 1) several satellites orbiting and
  providing strong signals 2) ground monitoring
  stations, and 3) a hand held (or larger)
  receiving GPS unit.

22
Types of Maps 300

• The Robinson map projection is considered very
  useful. Why?
• Answer- Most distances, sizes
• Return to board

23
Types of Maps 400

• Since Earth is a circle with a circumference of
  360º degrees, what would be diameter of Earth in
  kilometers ? (Round it up to the next thousand to
  obtain the actual number)
• Answer- 360 x 111km 39,960 km (rounded it is
  40,000 km, the estimated diameter of Earth)
• Return to board

24
Types of Maps 500

• What type of maps is so accurate for small areas
  that is frequently used for road maps? (it is not
  very accurate for large areas.
• Answer- A conic projection.
• Return to board

25
Types of Maps 200

• You are looking at a map on your computer, and
  you zoom in to view more detail. How do the scale
  change, and how do the distance between places
  change on the map and on Earth?
• Answer- The map distance in the scale and between
  places in the map will increase. The distance
  between places in Earth will not change.
• Return to board

26
Types of maps 100

• The technology that collects data about Earth
  from far above the Earths surface (using
  satellites) is called.
• Answer- Remote sensing (make sure you understand
  why is not GPS)

Wild Card 300

• If a ship using sonar detects a relatively short
  length of time between emission of sound wave and
  reception of its return, what can be said about
  the oceans topography below?
• Answer- The ship is above a relatively shallow
  area.
• Return to board

28
Wild Card 200

• The Equator divides Earth in 2 equal halves.
  Because of this, the Equator is the only latitude
  line that is a Great Circle. What are the names
  of the 2 halves?
• Answer Northern and Southern hemispheres.
