CONS 127 Midterm Exam Questions
And Answers Rated 100% Correct!!!
Latitude CORRECT ANSWERS horizontal lines
angle that describes the north south position
Longitude CORRECT ANSWERS vertical lines
angle that describes the east west position
Prime Meridian CORRECT ANSWERS Greenwich
origin of the measures of longitude (0 degrees of longitude)
Parallel CORRECT ANSWERS circle connecting all locations with a given latitude
3 ways the earth's shape can be mathematically defined CORRECT ANSWERS sphere,
ellipsoid, geoid
The only correct representation of the Earth's surface CORRECT ANSWERS geoid
Equivalent projection + example CORRECT ANSWERS allows for comparing the
surfaces of the Earth within the map, since the areas of the continents are accurate
the shapes of the continents are distorted
ex. Mollweide or Gall-Peters
Conformal projection + example CORRECT ANSWERS the angles between positions
are preserved so that ships can navigate from place to place and know how far it is
going to be from where they are
land area is distorted
ex. Mercator
Considering the case of Africa and Greenland, describe how map projections might
influence the perspective of the map viewer? CORRECT ANSWERS mercator
projection is not an equal-area projection and distorts the relative size of landmasses,
exaggerating the poles
How was the metre first defined? CORRECT ANSWERS one ten-millionth the size from
the length of the equator to the North Pole
, How is the metre defined now? CORRECT ANSWERS defined as the length that light
travels in a fraction of a second
The name of the unit that is equal to 1000nm CORRECT ANSWERS 1 micrometre
Small scale map CORRECT ANSWERS covers a more area, but with not as much as
detail
Large scale map CORRECT ANSWERS covers a small area but with great detail and
accuracy
Two ways scale can be indicated on a map CORRECT ANSWERS bar scale
ratio scale
What kind of map scale would be appropriate for representing large countries and/or
continents? For a city? For a neighbourhood? CORRECT ANSWERS 1:2000 (large
scale... ) is suitable for a neighborhood and the smaller the scale gets it gets, the more
suitable it is for covering extensive landmasses. Scale of 1:2,500,000 shrinks things to
be the so small, its used to cover very large extents
3 devices that can measure distances at different scales CORRECT ANSWERS
microscopes, telescopes and satellites
Relative positioning CORRECT ANSWERS when you give someone directions by using
where the location is close to, street names, addresses, etc.
also called dead-reckoning
Absolute positioning CORRECT ANSWERS using latitude, longitude and/or coordinates
to show where a location is
also called position fixing
Geodetic marker CORRECT ANSWERS a way of mapping the Earth's surface
give us accurate information on their relative and absolute position, and by triangulation,
the points are used to find other points
In ocean navigation, which is easier to calculate, latitude or longitude? CORRECT
ANSWERS Latitude is easier to calculate because you can use the stars to measure
your position
The critical measurement to obtain an accurate longitude CORRECT ANSWERS time
