### MSBSHSE Class 9 Social Science Geography Chapter 1 Textbook Exercise Questions

Q 1. Give reasons why the following sentences are right or wrong:

(1) The main aim of distributional maps is to show location.

(2) In choropleth maps, only one value is assigned to the sub-administrative unit.

(3) In choropleth maps, colours/tints do not change according to the values of the variables.

(4) Choropleth maps are used to show altitudes.

(5) Isopleth maps are used to show population distribution.

(6) In dot method, every dot should have an appropriate scale.

(7) Isopleth maps are not made using isolines.

(8) Distribution of various geographical elements can be shown using dot method.

Answer 1: The statement is wrong. Distributional Maps indicate the distribution of a particular feature in a given area. Through distributional maps we can show various variables related to distribution in districts/talukas to wheat production in different farms in a single village, distribution of temperature, rainfall, population, etc.

Answer 2: The statement is correct. In the Choropleth method, only one value is given to one sub administrative unit in a region. The smallest and the largest values of the given data of the variable are taken into consideration.

Answer 3: The statement is wrong. In choropleth maps, the data regarding various geographical variables is shown by shades or tints of various colours.

Answer 4: The statement is wrong. Choropleth maps are used to show the distribution of various geographical variables.

Answer 5: The statement is wrong. In Isopleth maps, the distribution was shown with the help of lines showing equal values. When the distribution of a variable is continuous, the isopleth method is then used to show its distribution. For example, altitude, temperature, rainfall, etc.

Answer 6: The statement is right. A dot map is prepared using statistical data. While preparing dot maps, only data gathered through counting is used. The way a variable is distributed throughout the region, the dots are used to show its distribution on the map.

Answer 7: The statement is wrong. Isolines are lines, which join the places having the same data on a map like lines joining places having equal rainfall.

Answer 8: The statement is wrong. In the dot map, the distribution is usually shown with the help of dots whose value is predetermined. To decide the value of the dot, the appropriate scale is chosen. Additionally, aspects of the region such as water sources, physiography, transport system, etc are considered to place the dots on the maps.

(1) Explain the use and types of distributional maps.

(2) Differentiate between choropleth and isopleths methods.

(3) Explain with reasons the method, which is best suited to show the distribution of population in a region.

Answer 1: Distributional Maps are called thematic maps. Through these maps, distribution of various variables in a region is shown, distribution of temperature, rainfall, population, etc. is shown on the map according to the data of these variables.

The uses and types of distributional maps are:

Dot Maps – A dot map is prepared using statistical data. While preparing dot maps, only data gathered through counting is used. The way a variable is distributed throughout the region, the dots are used to show its distribution on the map. For example, the population of a region, the distribution of cattle, etc.

To show distribution through the dot method, the value of a dot has to be determined. To do that, the lowest and the highest values of a given variable in a region are taken into consideration. Accordingly, the number of dots is determined. Also, we need to consider the size of the dot, the density of the variable and the scale of the map. The dot method is most suitable for that variable which is freely scattered across the region.

Choropleth Maps – In these maps, the data regarding various geographical variables are shown by shades or tints of various colours. While making such maps, the data used for different variables are obtained, through various processes such as measurement, surveying, etc. In this method, only one value is given to one sub administrative unit in a region. The smallest and the largest values of the given data of the variables are taken into consideration.

Isopleth Maps – In these maps, the distribution was shown with the help of lines showing equal values. When the distribution of a variable is continuous, the isopleth method is then used to show its distribution. For example, altitude, temperature, rainfall, etc. For these maps, we need to obtain the accurate data regarding the altitude, temperature, rainfall, etc. of some places in a region.

Answer 2: The difference between choropleth and isopleths methods are as follows:

 Choropleth Method Isopleths Method In these maps, the data regarding various geographical variables is shown by shading/ tints of various colours. In these maps, distribution is shown with the help of lines showing equal values. In this method only one variable is given to one sub administrative unit in a region. A variable is continuous, the isopleths method is then used to show its distribution. Choropleth method is used to show the distribution of population, density and distribution of cattle. Isopleth method is used to show the distribution of temperature, altitude and rainfall of a region.

Answer 3: Dot method or dot map is the best way to show the distribution of the population in the region. Using the dot method, you can easily find the exact population number in a particular region. In the dot map, the distribution is shown with the help of dots whose value is pre-determined by choosing the appropriate scale. This representation of data is highly possible for several variables, such as populations that are freely scattered across the region.

Q 3. Which method will you use for the following information?

(1) Taluka Wise wheat production in the district

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

(3) Distribution of domestic animals in the State

(4) The distribution of population density in India

(5) Temperature distribution in Maharashtra State.

Answer 1: Taluka wise wheat production in the district can be represented by the dot distribution map.

Answer 2: Distribution of the altitude of the land in the district can be represented by the isopleth maps.

Answer 3: Distribution of domestic animals in the State can be represented by the dot distribution map.

Answer 4: The distribution of population density in India can be represented by the choropleth map.

Answer 5: Temperature distribution in Maharashtra State can be represented by an isopleth map.

Q 4. Study the population distribution map of Kolhapur district and answer the following questions:

(1) Which 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.

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

(4) Which Taluka has the least population?

Answer 1: The Dot method has been used to show the distribution of population in the given Kolhapur district map.

Answer 2: According to the given population distribution map of Kolhapur District, the population depicted in the map exhibits the densely populated cities in the North Eastern side of Kolhapur district which gradually declines as it moves towards the South. As we move towards the North West or West we observe sparse population with Gaganbawada being the least populated region of the district. Kolhapur city is the most populated city in the district and has more than a 10 lakh population.

Answer 3: According to the given population distribution map of Kolhapur District, the population depicted by the largest circle is twenty lakhs.

Answer 4: According to the given population distribution map of Kolhapur District, the Taluka ,which is observed having the least population is Gaganbawada, located in Maharashtra India. It is shown having a population of 40,000.
