• In Isopleth method the distribution was shown with the help of lines showing equal values.

(3) Dot method is suited to show the distribution of population in a region. Because it shows the number of values in specific dots, to do that, the lowest and the highest values of given variable in a region are taken into consideration.

Question no – (3) 

Answer : 

(1) Talukawise wheat production in the district

= Dot method.

(2) Distribution of the altitude of the land in the district.

= Isopleth method.

(3) Distribution of domestic animals in the State

= Dot method.

(4) The distribution of population density in India

= Choropleth method.

(5) Temperature distribution in Maharashtra State.

= Isopleth method.

Answer : 

(1) Which method has been used to show the distribution of population in the district?

= Dot method has been used to show the distribution of population in the district.

(2) Explain the direction wise distribution of population from dense to sparse.

= Consequent upon the given population distribution map of Kolhapur district the population illustrated in the map indicates the densely populated cities in the north eastern side of the district which slowly reduces as it moves towards the south. By moving towards west or north west we see sparse population with the least populated Gaganbavada. With more than 10 lakhs population the Kolhapur city is the most populated city because no other city is not populated than Kolhapur.

(3) What is the population shown by the largest circle ? Which place is that?

= The largest circle shows us the population of Twenty Lakhs.
In this map Kolhapur city is the most populated city with the largest circle.

(4) Which Taluka has the least population?

= In consonance with the map Gaganbavada taluka has the least population.
