Detailed explanation-1: -As a rule of thumb, the V-shaped contour is pointing upstream (the opposite direction from the flow of a stream or river). The āVā shape contours indicate streams and drainage.
Detailed explanation-2: -If the numbers associated with the contour lines are decreasing, there is a decrease in elevation. As a contour approaches a stream, canyon, or drainage area, the contour lines turn upstream. They then cross the stream and turn back along the opposite bank of the stream forming a āv".
Detailed explanation-3: -A line passing through the peak point of the contour drawing is called a section line. A contour line is an imaginary line joining places that have the same height above sea level and this method of representing height on the map using contours is called contouring.
