lecture 2- this is geography Flashcards
two basic parts of geography
space and place
space=
physical location, gap or interval between objects or points
place=
a space have attached human meaning to
ex. a house
geagraphy means “—”
earth writing
what are the 6 types of scales in geography?
- personal- local- regional national- international- global
Think of scales as a gradient, where does one finish and the next one start?
map scale
what are maps used for?
reference tool
2D representation of earth’s surface
communication tool
cartography
meridians=
longitude
ex. north to south pole
parallels=
latitude
ex. the equator
why are flight routes curved when we get further from the equator?
not the best map to use
v good for ships but not good for fuel efficiency
what 2 “timings” do we use in maps?
Coordinated Universal Time (UTC)
Greenwich Mean Time (GMT)
what is the most used map?
Mercator projection
Mercator projection map properties
= distorts size, preserves shape,
areas near the poles appear much larger than they actually are!
When doing a map projection, you need to choose if you value to preserve —, —, or —
size, shape or direction
Mercator projection origins
- preserves orientation very well, was made to help sailors find a reference point to navigate in the oceans
- getting further north or south it becomes almost impossible to use because it gets distorted, that is why Greenland is huge on the map!
what area of the world does the mercator projection map put prevalence on?
- puts prevalence on Europe and the northern and southern hemisphere
-we have been so used to the orientation of the counties on this map, perhaps this has influenced global politics
Topographic map
or hiking etc., useful for showing the elevation, high and low points, using contour lines or isobars, closer lines= steeper elevation
