Latitude - ANS horizontal lines
angle that describes the north south position
Longitude - ANS vertical lines
angle that describes the east west position
Prime Meridian - ANS Greenwich
origin of the measures of longitude (0 degrees of longitude)
Parallel - ANS circle connecting all locations with a given latitude
3 ways the earth's shape can be mathematically defined - ANS sphere, ellipsoid, geoid

, Equivalent projection + example - ANS 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 - ANS 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? - ANS mercator projection is not an equal-area
projection and distorts the relative size of landmasses, exaggerating the poles
How was the metre first defined? - ANS one ten-millionth the size from the length of the
equator to the North Pole
How is the metre defined now? - ANS defined as the length that light travels in a fraction of a
second
The name of the unit that is equal to 1000nm - ANS 1 micrometre
Small scale map - ANS covers a more area, but with not as much as detail
