CONS 127 MIDTERM EXAM 2025/2026
QUESTIONS AND ANSWERS 100% PASS
Horizontal lines
angle that describes the north south position - ANS Latitude
vertical lines
angle that describes the east west position - ANS Longitude
Greenwich
origin of the measures of longitude (0 degrees of longitude) - ANS Prime Meridian
circle connecting all locations with a given latitude - ANS Parallel
sphere, ellipsoid, geoid - ANS 3 ways the earth's shape can be mathematically defined
geoid - ANS The only correct representation of the Earth's surface
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 - ANS Equivalent projection + example
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 - ANS Conformal projection + example
mercator projection is not an equal-area projection and distorts the relative size of landmasses,
exaggerating the poles - ANS Considering the case of Africa and Greenland, describe how
map projections might influence the perspective of the map viewer?
one ten-millionth the size from the length of the equator to the North Pole - ANS How was
the metre first defined?
defined as the length that light travels in a fraction of a second - ANS How is the metre
defined now?
1 micrometre - ANS The name of the unit that is equal to 1000nm
covers a more area, but with not as much as detail - ANS Small scale map
covers a small area but with great detail and accuracy - ANS Large scale map
bar scale
