Intro to Physical Geography Lab 3: Topographic Maps & Relief
dam
a depression uphill and a canyon would indicate a
low relief
a region that is mostly flat would have
high relief
a region with steep cliff and deep valleys would have
isobars
air pressure; common in weather
topographic profile
change from overhead view to side profile select a transect across terrain plot elevation across the transect's horizontal distance commonly used in trail books to show trail difficulty
total relief
change in elevation between highest ("x") and lowest point on entire map
local relief
change in elevation between two specified points
depression
closed contour shape with ticks indicates a
hill/summit
concentric contours indicate a
terrain
describes how the surface elevation changes across the landscape
relief
distance between the highest and lowest points on a map can describe how quickly the elevation is changing
contour lines
how elevation is shown on topographic maps type of isoline that show consistent elevation all points on this have the same elevation printed in brown; make a closed shape though may run off the map if it is too small
isolines
line on a map connecting points of identical value
isogons
magnetic declination
topographic maps
maps that display changes in elevation a map of physical features + contour lines
contour interval
separate multiple contour lines with this (a consistent change in elevation) will be the same for the same map and different among different maps
isotherms
temperature; common in weather
index contours
thicker lines that have their elevation printed on the map usually labeled with elevation
upstream; downhill
this v-shaped pattern (indicative of a stream) points___ and water flows___
since the spacing of contour lines=the slope of the land, then the closer the counter lines the steeper the land is
what generalization would you make about the relationship between the closeness of contour lines and real-world terrain steepness
v-shaped pattern
when a contour line crosses a stream, it makes a
