what are topographic maps
maps that indicate changes in elevation for that particular area
whats another name for topographic maps
contour maps
what is elevation
height above sea level, altitude
what is a contour line
a line that connects points of equal elevation
whats a contour interval
the change in elevation from one contour line to the very next contour line
what are hacture lines
contour lines that indicate a hole/depression/crater or decrease in elevation
if the contour lines are close together what does that say about the land/area
its steep
if the contour lines are spread out what does that say about the land/area
its flat
if there is a river which way do the comtour lines point in comparison to the way the river flows
the contour lines point in the opposite direction
what does gradient equal
distance divided by change in elevation
whats the first step to making a topographic map
put a peice of paper along the line
whats the second step to making a topographic map
mark each contour line with a tick mark on the paper
whats the third step to making a topographic map
place sheet of paper with elevations noted besides the tick marks
