geo terms 3 Flashcards
aerial photograph
image taken from an aircraft of an area of the surface
area reference
a sequence of 4 numbers that helps locate large features on a topograohic map
aspect
the direction that a slope faces ( slope as in mountain)
atlas
a book of maps
bar graph
a graph where bars are drawn proportionately in length to the value they represent
barometer
measures atmospheric pressure
bearing
direction given in terms of degrees from the nortgh
cardinal points
main compass points north south east west
cloropleth map
map that shows relationship between quantity/ densitiy and area using coloring or shading
climate
the long term weather pattern of a region
climate graph
shows the max and min avergae daily temperatures. shows precipitation data
column graph
kind of bar graphs where bars are drawn vertically
compass
an instrument used to determine direction
countour line
line that jpins places equal in height above sea levels
countour map
tu represent a part of earth using lines that say that all places are of equal height above / below sea level
cross section
side view/ profile of land
density
population per unit area ( 1km2)
distance
length from one point to another
distribution
arrangement of items in an specific area
dot map
uses dots to show the distribution of a feature
elevation
height of a place above mean se level
equator
line drawn around the boradest part of the earth, middle part of the north and south.
flowline map
map with arrows that show the movement of places/ goods / info. also show the qualoty of this movement
gradient
a measure of the steepness of a slope
grid
pattern of lines on a chart or map that helps readers identify exact location and distribution patterns
grid reference
sequence of 6 number sused to locate features on a topographic map
hachures
lines to show the steepness and direction of a slope. so gradient and aspect
isobars
lines in weather maps joing places of same atmospheric pressures
landform
natureal feature of earths surface
landscape
apparance of an area bc u join elements such as landforms and vegetation and rivers anf industry and agriculture transportation settlements
latitude
position of a point on the earth´s surface expressed as angular distance north and south. 90 deg from equator
legend
key to map or graph, set of symbols
line graph
shows relationship between 2 variables by using curved lines
line of sight
that u can see a point in the surface of the earth clearly. no obstruction from landforms
linear pattern
when features or points have an arrangementn in the form of a line
local relief
dif between highest and lowest places in a specified area
location
position of a featrure that u can tell by t¿using the grid( coordinates) or relation to another place
longitude
position of a point expressed a sthe angular distance west and east from the prime meridian and 180 deg
map
a graphical representation of an area. u draw it to scale and flat
map projection
the grid that states latitudes and longitudes on orderto draw the spherical earth into a flat shit
oblique arial photo
photograph from aitcraft but the photo is taken in an oblique angle
pie graph
the circle that is divided into dif segments radiating from the center of the circle. proportional to the values they represent
population pyramid
bar graoh that shows distribution by gender and age
precis map
sketch that highlights one particular feature of a map
quadrants
division of a map in 4 parts based on the compass points
relative location
location of a place but yousay it in relationship to other features or places near
relief
relieve
shape of the land and you show height and gradient differences of a landscape
remote sensing
infor about the surface that is taken aerially like form a sattellite ot a radar
satellite image
sensor gathers image from measuring electromagnetic radiation. they transform it to digital. tey sent it to ground. ground transfros itnto image.
scale
ratio / relationship bweteen a lineat measurement of the map and corresponding distance on earths surface
scatter graph
a graph where 2 variables / sets of data are placed and the strngth of the relationship is showed
settlement
place inhabited by people. perminantely or semi permamnetntly
site
place where something is located, including physical setting
situation
location of a feature or place relative to other locations
so basically same as relative location ok.
picture graph
illustrations are used to represent data. symbols are used for quantitiy or values
sketch map
drawn in the field or from areal photo, to analyze landscaoes
spot height
point giving the exact height/ alttiute above sea level
ternary graph
triangle graph where 3 sets of variables make 100%
thematic map
map that shows specific distribution of something like a gegraphical theme. can be population or vegetation
time zones
global divisions, 15 deg of longitude, time at teh central meridian of the divion represents the time for the whole division
topographic map
