CONS 127 Finals Sample Questions & Answers
Solved 100% Correct.
What is latitude and longitude?
Latitude is the angle that describes the north-south position. Longitude is the angle that describes
the east-west position
Where is the prime meridian?
It is located at 0 degrees of longitude
What is a parallel?
A circle connecting all locations with a given latitude
What are the 3 ways the earths shape can be mathematically defined?
Ellipsoid, sphere and geoid
What is the only correct representation of the earths surface
On a globe
What is the main difference between an equivalent and conformal projection?
Conformal maps have distortions of the areas of the countries but manage to keep the angles
preserved so its good for sea navigation. Equivalent maps keep the areas of the counties
preserved, but distort the shape of the countries
Considering the case of Africa and Greenland, describe how map projections might
influence the perspective of the map viewer?
, Came from the idea of Eurocentric mapping in which early maps focused more on European
countries, making them appear bigger. Its argued that Africas importance has been diminished in
part due to map projections which make the continent appear much smaller than it actually is. On
a mercator map, Greenland appears to be basically the same size as Africa, when in reality
Greenland is much smaller than Africa.
How was the meter first defined?
One ten millionth of the distance from the equator to the north pole
How is the meter defined now?
The length of the path traveled by light in vacuum during a time interval of 1/299,792,458 of a
second
What is the name of the unit which is equal to 1000nm?
1 micrometer
Which covers more area, a small or large scale map?
A small scale map will cover a larger area with coarse detail
What are 2 ways a scale can be indicated on a map?
Graphic scale/Bar scale and fractional scale/ratio scale
What kind of map scale would be appropriate for representing large countries and/or
continents? For a city neighbourhood?
Continental maps use 1:20,000,000 scales whereas city neighbourhoods use 1:30,000 scales for
cities and 1:15,000 for neighbourhoods
