one number below what the actual elevation would be if there was another contour line

possible elevation of an area at the top of a hill /mountain

a range value of elevation from the last contour line up to the last possible value before another contour line would be drawn

elevation

height above sea level

stream flow

always flow opposite the "bends" , v-shaped lines in the contour lines

relief

difference in elevation between highest and lowest parts of an area
