Question

How is distribution shown in the isopleth method ? Give any 3 examples of some frequently drawn isopleths and explain about what all are the conclusions we can draw from isopleth maps.

Answer 1

Instructions:

• Define Isopleth method(1M).
• List out 3 examples of isopleths drawn(1M).
• List out three conclusions(3M)

Solution :

• Isopleth method is the method in which geographical facts and values are shown by drawing the lines representing equal values on a map.

• Some frequently drawn isopleths are contours, isobars, isohyets etc.

• The following conclusions are drawn from isopleth maps:
  • If the lines are closer to each other then the change in the variable is steep
  • If the lines are away from each other, then it is gentle.
  • We also get an idea of the natural trend of the distribution of the variable with the help of this map.
