Question

Write a short note on Contours.

Short Note

Solution

Some basic features of contour lines are:

  • A contour line is drawn to show places of equal heights.
  • Contour lines and their shapes represent the height and slope or gradient of the landform.
  • Closely spaced contours represent steep slopes while widely spaced contours represent gentle slopes.
  • When two or more contour lines merge with each other, they represent features of vertical slopes such as cliffs or waterfalls.
  • Two contours of different elevations usually do not cross each other.
