CONS 127 Final Exam UPDATED
ACTUAL Questions and CORRECT
Answers
Latitude - CORRECT ANSWER✔✔- Angle describing East/West position
Longitude - CORRECT ANSWER✔✔- Angle describing North/South position
Parallel - CORRECT ANSWER✔✔- Circle connecting locations within a given latitude
Three ways we can describe Earth's shape - CORRECT ANSWER✔✔-
Sphere/ellipsoid/geoid
Only correct representation of Earth's surface - CORRECT ANSWER✔✔- geoid
Main difference between equivalent and conformal projection - CORRECT ANSWER✔✔-
Equivalent- Areas of countries and continents are preserved. Conformal projection- angles
between positions are preserved.
How was a metre first defined? - CORRECT ANSWER✔✔- One ten millionth of distance
from the Equator to the North Pole
How is it defined now? - CORRECT ANSWER✔✔- Based on the speed of light and defined
by the length of the path travelled by light in a vacuum during a time interval of 1/299 792
485 of a second
What is the name of the unit which is equal to 1000 nm? - CORRECT ANSWER✔✔- 1
micrometer
Which covers more area, a small or a large scale map? - CORRECT ANSWER✔✔- Small
scale map
, What are two ways scale can be indicated on a map? - CORRECT ANSWER✔✔- graphic
scale and fractional scale
What kind of map scale would be appropriate for representing large countries and/or
continents? For a city neighbourhood? - CORRECT ANSWER✔✔- Graphic scale used for
small scale maps. Verbal scale for city/neighbourhood.
What are two ways scale can be indicated on a map? - CORRECT ANSWER✔✔- Graphic
scales or fractional scales
Who wrote the soundtrack to The Powers of Ten? - CORRECT ANSWER✔✔- Elmer
Bernstein
What is relative positioning? Vs absolute positioning? - CORRECT ANSWER✔✔- Relative-
relates to landmarks and other features around you. Absolute- uses coordinates, fixed position
Prior to 1800, what was the underlying principal behind positioning? - CORRECT
ANSWER✔✔- Dead reckoning (use previously determined position and advancing the
position based on estimated speed over time)
What are the two aspects of a position that need to be measured? - CORRECT
ANSWER✔✔- ??
Name some 3 devices which can measure distances at different scales? - CORRECT
ANSWER✔✔- Electron microscope, optical microscope, cameras
What is a geodetic marker? - CORRECT ANSWER✔✔- Basis for mapping of Earth's surface
In Ocean navigation which is easier to calculate, latitude or longitude? - CORRECT
ANSWER✔✔- Latitude is easier to calculate
Describe how the altitude-intercept model can be used to find a position on the Earth's
surface. How does this method differ from previous positioning methods? - CORRECT
ANSWER✔✔- Requires the observer knows the time at Greenwich at the moment of
