FINALS Flashcards
map projection
an attempt to portray the earth on a flat surface . projections become distorted because the earth is a sphere
map scale
element of map that shows how a unit of distance on a map relates to real distnace on earth
compass rose
a diagram on the map that shows directions
longitude
the lines on a map or globe that measure vertically
lattitude
the horizontal lines
equator
horizontal line at zero degrees
prime meridian
the meridian of longitude at zero degrees
hemisphere
one half of a sphere
relative location
the location of something compared to something else
absolute locatiopn
where something is exatcly one arth
physical map
shows physical feautures of an area suchas river and elevationb
political map
shows state and national boundaries
thematic map
shows a single theme connected to a geographic area
plate tectonics
tectonic plates that make up the earth’s crust
convergent boundaries
boundaries that converge to create mountains
divergent boundaries
boundaries that rift valleys
transform boundaries
the plates are moving opposite directions …… these cuase eathquakes and volcanoes
weathering
works by breaking things down at the earth’s surface. wind , water , ice and living things cause this
erosion
when rock sand and soil are broken into smaller pieces CARRYING IT AWAY
deposition

peninsula
land surrounded by water on three sides
ithmus
narrow strip of land with water on both sides connecting two large pieces of land
glacier
big amount of ice
river system
rivers and their tributaries
mesa
elevated flat top
what are mesa shaped by
erosion and convergent boundaries
what is a gulf
a very large bay
weather
the daily conditions of the atmosphere
climate
the average weather over time
relationship between the tilt and the seasons
the tilt cause seasons that are separated by the equator
5 major factors that affect climate
lattitude, ocean currents and wind, contientialty, elevation, mountain barrier,
why is latiitude the most important factor that affects climate
because the further from the equator the colder and drier it gets
what is conteintiality
how far inland something is
what is a climograph
graph that shows average temp and prec. for an area
what climates are near the equator
tropical
what vegatation near the equator
troppical rain forest
what climates near the poles
cold, dry and arid
population pyramid
divided into sexes from youngest to old to show populatio0n change
