CONS 127 Study Questions & Answers Solved
100% Correct.
who drew the first map and why was it significant
Ptolemy, first map with latitude/longitude
latitude
angle that describes the north-south position
parallel
circle connecting all locations with a given latitude
pole
points where earth's axis of rotation meets it's surface
equator
intersection of the earth's surface with the plane perpendicular to the axis of rotation and midway
between the poles. BIGGEST PARALLEL.
arctic circle
northernmost latitude in the northern hemisphere where the sun can remain continuously above
or below the horizon for 24 h
Antarctic circle
southernmost latitude in the Southern Hemisphere where the sun can remain continuously above
or below the horizon for 24h
,tropic of cancer
northernmost circle of latitude where the sun can be directly overhead
tropic of Capricorn
southernmost circle of latitude where the sun can be directly overhead
earth's axial tilt
spins as 23.44 tilt
longitude
angle that describes the east-west position
meridian
half of an imaginary great circle, terminating at the North Pole and the south poles, connecting
points of equal longitude
prime meridian
-greenwich
-origin of the measures of longitude (zero degrees of longitude)
shapes of the earth
-perfectly a sphere where earth's radius is constant
-ellipsoid: more of a ellipse where earth is flattened at the poles and bulges at the equator
-geoid: physical approximation of the earth using gravity readings and reads surface elevations
map projection
, -set of mathematical formulas and equations that enable earth's curved surface to be shown on a
flat map
cylindrical projections
-earth projected onto a cylinder
-whole world maps are rectangular
-distortion at the poles
conic projections
-earth is projected onto.a cone
-good for representing parts of the earth
planar projections
-earth is projected on a plane
-lost of distortion towards the edges
cylinderical- conformal
-angles between positions preserved so good for sea navigation
-distortion of countries/continents
-mercator
conic- equivalent/equal areas
-area of the countries/continents preserved
-enables direct surface comparisons within the map
-shape of countries/continents distorted
-gall-peters
