Maharashtra Board Class 9 Geography Chapter 1 Distributional Maps Solutions

Give Reasons Why the Following Sentences Are Right or Wrong:

 

Question 1. The main aim of distributional maps is to show location.
Answer: Wrong. The main aim of distributional maps is to show the distribution of variables like temperature, rainfall, population, etc. These maps help us analyze the spatial patterns of various geographical elements across a region.
In simple words: Distributional maps do not just show where a place is. Instead, they show how things like people, rain, or heat are spread out across an area.

🎯 Exam Tip: Always state clearly whether the sentence is 'Right' or 'Wrong' at the very beginning of your answer to secure full marks.

• Distribution maps are type of thematic maps.
• These maps are prepared with special themes like the distribution of various variables in a particular region.
• They make use of different methods to show the distribution of variables like temperature, rainfall, population, etc.

Thus, the main aim of distributional maps is to show the distribution of variables in a particular region.

 

Question 2. In choropleth maps, only one value is assigned to the sub-administrative unit.
Answer: Right.
1. In choropleth maps, the data regarding various geographical variables is shown by shading or using tints of various colours.
2. After gathering the data for a selected variable, five to seven classes are made considering the smallest and the largest values.
3. Each class is assigned a tint of the same colour or black-and-white patterns. This helps in maintaining visual consistency across the map.
4. A particular value shown by a predecided tint of colour can represent only a particular region or group of region.
Thus, in choropleth maps, only one value is assigned to sub administrative unit.
In simple words: In a choropleth map, each small district or area gets only one color shade. This shade represents a single range of data, like population density, making the map easy to read.

🎯 Exam Tip: Remember that choropleth maps use shades or tints of the same color to represent data ranges, and each sub-administrative unit can have only one representative value.

 

Question 3. In choropleth maps, colours/tints do not change according to the values of the variables.
Answer: Wrong. In choropleth maps, colours/tints change according to the values of variables. Higher values are typically represented by darker shades, while lower values use lighter shades.
• In choropleth maps, the smallest and the largest values are taken into consideration and after that 5-7 classes are made.
• Each class is assigned a unique tint of the same colour or black and white pattern.
In simple words: The colors on a choropleth map actually change based on the numbers. For example, areas with more rainfall will have darker blue shades, while dry areas will have lighter shades.

🎯 Exam Tip: Clearly state whether the statement is 'Right' or 'Wrong' first, and then provide the geographical reasoning to secure full marks.

 

Question 4. Choropleth maps are used to show altitudes.
Answer: Wrong. Isopleth maps and not the choropleth maps are used to show altitude. These maps help us visualize geographic variations more effectively.
• When the distribution of a variable is continuous like the altitude, the isopleth method map is used.
• Isopleth maps use lines joining the locations having equal values and hence are useful to show the change in altitude in the region.
• When the distribution of a variable is discontinuous, the choropleth method map is used to show its distribution, eg. distribution of population, domestic animals, etc.
In simple words: Choropleth maps use colors or shades for different administrative areas, but altitude changes smoothly across land, so we use lines (isopleth maps) to show height instead.

🎯 Exam Tip: Remember that continuous data like altitude or temperature always uses isopleth (line) maps, while discontinuous data uses choropleth or dot maps.

 

Question 5. Isopleth maps are used to show population distribution.
Answer: Wrong. Dot method maps or choropleth method maps are used to show population distribution. Population is spread out unevenly across cities and villages, making it discontinuous.
• Distribution of a population is discontinuous.
• Isopleth method maps are used to show the distribution of variables which are continuous. For eg. altitude, temperature etc.
• Thus, isopleth method maps are not used to show population distribution.
In simple words: People do not live in a perfectly smooth, continuous spread everywhere, so we use dots or shaded areas rather than continuous lines to show where people live.

🎯 Exam Tip: Clearly state whether the variable is continuous or discontinuous to justify your choice of map method.

 

Question 6. In dot method, every dot should have an appropriate scale.
Answer: Right. The size of the dot is decided as per the value of a variable that is freely scattered across the region. This ensures that the map remains clear and easy to read without overcrowding.
In simple words: Each dot on a dot map represents a specific number of things (like 100 people), so the size and value of the dot must be carefully chosen to fit the map.

🎯 Exam Tip: When explaining the dot method, always mention that the scale determines the value represented by each single dot.

 

Question 7. Isopleth maps are not made using isolines.
Answer: Wrong. Isopleth maps are made using isolines. Isolines are lines joining places of same values of a given variable in a map. Since, isopleth maps are also prepared in the same method, we can say that they are made using isolines. These lines help us visualize continuous data across a region easily.
In simple words: Isopleth maps use lines called isolines to connect places with the same values, like temperature or rainfall. This helps us see patterns clearly.

🎯 Exam Tip: Remember that 'iso' means equal, so isolines connect points of equal value on a map.

 

Question 8. Distribution of various geographical elements can be shown using dot method.
Answer: Wrong. Distribution of various geographical elements cannot be shown using dot method. Distribution of geographical elements which are freely scattered across a region can be shown using a dot method. Distribution of variables like population, minerals, cattles etc., are freely scattered hence can be shown on a dot method map. Whereas the distribution of variables like rainfall, altitude, temperature etc. which are continuous, cannot be shown using a dot method map. Therefore, the choice of mapping method depends entirely on the nature of the geographical data.
In simple words: The dot method is only used for things we can count individually, like people or animals. Continuous things like temperature or rainfall cannot be shown with dots.

🎯 Exam Tip: Clearly distinguish between discrete data (like population) and continuous data (like temperature) when choosing mapping methods.

2. Answer in Brief

 

Question 1. Explain the use and types of distributional maps.
Answer:
(a) Use of distributional maps: The distributional maps are useful for explaining the patterns of distribution of a particular geographical variable. These maps serve as essential tools for geographers and planners to analyze spatial data.
(b) The types of distributional maps : The following are the types of distributional maps.
1. Dot Method: The distributional map based on statistical data, made by this method, make use of dots of a pre-decided size to show the distribution of a particular variable, e.g. Dot method map is used to show the population of a region, distribution of cattle etc.
In simple words: Distributional maps show how different things, like population or rainfall, are spread across an area. One common type is the dot method, which uses dots to represent quantities of items like people or livestock.

🎯 Exam Tip: When explaining distributional maps, make sure to define their purpose first before listing the specific methods like the dot method.

2. Choropleth Method: The distributional map made by this method makes use of shades or tints of various colours, to show the distribution of a particular variable, e.g. Choropleth method map is used to show population density, types of forest cover, uses of land.

3. Isopleth Method: The distributional map made by this method makes use of lines joining locations or places having same or equal values of a particular variable, e.g. Isopleth method map is used to show altitude, temperature, rainfall.

 

Question 2. Differentiate between choropleth and isopleths methods.
Answer: The differences between the choropleth and isopleth methods of mapping are detailed in the table below, highlighting how each technique represents geographical data.

Choropleth Method	Isopleth Method
(1) In Choropleth method maps, the distribution of various variables are shown by shading or using tints of the same colour.	(1) In Isopleth method maps, the distribution of various variables are shown with the help of isolines.
(2) When the distribution of a variable is not continuous, the choropleth method is used.	(2) When the distribution of a variable is continuous, the isopleth method is used.
(3) Choropleth method is used to show population density, cattle distribution etc.	(3) Isopleth method are used to show altitude, temperature, rainfall of a region etc.

In simple words: Choropleth maps use different shades of colors to show data like population density, while isopleth maps use lines to connect places with equal values like temperature or rainfall.

🎯 Exam Tip: Presenting differences in a neat tabular format with clear headings helps you secure full marks easily.

 

Question 3. Explain with reasons the method which is best suited to show the distribution of population in a region.
Answer:
• The dot method of making a distributional map is best suited to show the distribution of the population in a region. This method ensures that highly populated areas are clearly visible through dense clusters of dots.
• The dots used in this method, are given a particular value which is determined by selecting a proper scale considering the spread of the values of the variables in the given region.
In simple words: The dot method is best for showing population because each dot represents a specific number of people, making it easy to see where many people live and where fewer people live.

🎯 Exam Tip: Always mention how the scale of the dots is determined when explaining the dot method for population distribution.

This method is best suited to show the distribution of the variables which are freely scattered as in the case of population distribution.

3. Which Method Will You Use for the Following Information?

 

Question 1. Talukawise wheat production in the district
Answer: Dot method. This method uses dots of uniform size to represent a specific quantity of wheat production across different talukas.
In simple words: We use the dot method because wheat production is scattered across different areas, and dots help show where more or less wheat is grown.

🎯 Exam Tip: Remember that the dot method is ideal for representing data that is distributed as discrete values across a region.

 

Question 2. Distribution of the altitude of the land in the district.
Answer: Isopleth method. This method is used because altitude is a continuous variable that changes gradually across the land.
In simple words: The isopleth method uses lines to connect places with the same height, making it perfect for showing land altitude.

🎯 Exam Tip: Use the isopleth method for continuous data like altitude, temperature, and rainfall where values change gradually.

 

Question 3. Distribution of domestic animals in the State
Answer: Dot method. This method is highly suitable for showing the count and distribution of freely scattered elements like domestic animals.
In simple words: We use dots to show where domestic animals are located because they are counted as individual numbers across different places.

🎯 Exam Tip: For counting items that are scattered (like animals or population), the dot method is always the best choice.

 

Question 4. The distribution of population density in India
Answer: Choropleth method. This method uses different shades or tints of the same color to represent different density ranges within administrative boundaries.
In simple words: The choropleth method uses different colors or shades to show which states have a high or low population density.

🎯 Exam Tip: Always choose the choropleth method when dealing with density or percentage data mapped within administrative boundaries.

 

Question 5. Temperature distribution in Maharashtra State.
Answer: Isopleth method. Temperature is a continuous geographical variable that is best represented using lines of equal value.
In simple words: Temperature changes smoothly from one place to another, so we use lines (isopleths) to connect areas with the same temperature.

🎯 Exam Tip: Remember that continuous variables like temperature and rainfall are always mapped using the isopleth method.

4. Study the Population Distribution Map of Kolhapur District and Answer the Following Questions:

 

Question 1. Which method has been used to show the distribution of population in the district?

Question 10. What is field report?
Answer: The report written on the basis of the information obtained from a field visit is known as field report. It serves as a structured presentation of the data and observations gathered during the trip.
In simple words: A field report is a written summary of everything you saw, learned, and collected during your geography field trip. It helps present your findings clearly.

🎯 Exam Tip: Define a field report clearly as a document based on direct observations and data collected during the visit.

Which Method Will You Use For The Following Information:

 

Question 1. The distribution of rainfall in the district of Nandurbar.
Answer: Isopleth Method. This method is ideal because rainfall is a continuous geographical variable that changes gradually across an area.
In simple words: We use the Isopleth method to show rainfall because rain changes smoothly from place to place, and this method uses lines to connect areas with the same amount of rain.

🎯 Exam Tip: Remember that continuous data like temperature, altitude, and rainfall are always represented using the Isopleth method.

 

Question 2. Cotton crop distribution in Maharashtra.
Answer: Dot method. This method is highly effective for showing how crops or population are scattered across a region.
In simple words: We use the dot method to show where cotton is grown because each dot can represent a certain amount of crop harvested in different areas.

🎯 Exam Tip: Use the dot method for representing distributed data like crops, livestock, or population across a map.

 

Question 3. Draw a map using the Dot Method:
Answer: [Students are expected to draw the map using the dot method based on their textbook guidelines.] This practical exercise helps in understanding how data values are converted into dots on a geographical map.
In simple words: This is a drawing activity where you place dots on a map to show where things are located based on given numbers.
