  • - Contour lines never cross. All lines on a contour line represent one elevation.
  • - The spacing of contour lines depends on slope characteristics. Contour lines that are close together show a steep slope. Contour lines that are far apart show a gentle slope.
  • - Contour lines that cross a valley or a stream are V shaped. The C points toward the area of the highest elevation. If a stream or river flows through the valley, the V points upstream.
  • -The tops of the hills, mountains, and depressions are shown by closed circles. Depressions are marked with short, straight lines inside the circle that point down slope to the depression.
