Imp Questions For All Chapters – Geography Class 9th
Short Questions
1. What is a distributional map?
Answer : A distributional map shows how things like population, rainfall, or industries are spread in an area.
2. Name the three types of distributional maps.
Answer : The three types of distributional maps are Dot Method, Choropleth Method, and Isopleth Method.
3. What is the dot method?
Answer : The dot method uses small dots to represent a fixed quantity of something, like population or crops.
4. How does the choropleth method work?
Answer : The choropleth method uses different shades of colors to show variations in a factor like population density.
5. What does the isopleth method represent?
Answer : The isopleth method uses lines to connect places with the same value of something, like temperature or rainfall.
6. Why are distributional maps important?
Answer : Distributional maps help in comparing different areas and making decisions for planning and development.
7. Which method is best for showing temperature distribution?
Answer : The isopleth method is best because temperature changes gradually and can be shown using smooth lines.
8. What does a dark color in a choropleth map represent?
Answer : A darker color represents a higher value, like a high population density or heavy rainfall.
9. What type of map is best for showing population density?
Answer : A choropleth map is best because it shows variations in population using different colors.
10. What is an isoline?
Answer : An isoline is a line that connects points with the same value, like temperature or height.
11. How does the dot method help in showing population distribution?
Answer : More dots in an area mean more people live there, making it easy to understand population distribution.
12. Why is it difficult to use dots for population maps?
Answer : Placing dots accurately is difficult, and overlapping dots can make the map confusing.
13. What is the main advantage of a choropleth map?
Answer : A choropleth map helps in comparing different regions easily using colors.
14. Which map method is used for studying rainfall distribution?
Answer : The isopleth method is used because rainfall varies smoothly over large areas.
15. What is the first step in making a distributional map?
Answer : The first step is to collect data about the factor being shown, like population or temperature.
Long Questions
1. What is a distributional map? Explain its uses.
Answer : A distributional map shows how different factors like population, rainfall, or industries are spread in an area. These maps help in planning, research, and comparisons. They are useful for governments, businesses, and students.
2. Explain the dot method with an example.
Answer : The dot method uses dots to show a fixed quantity of something. For example, if 1 dot = 1,000 people, an area with 50 dots means 50,000 people live there. This method is useful for showing population and crops.
3. What are the advantages and disadvantages of the choropleth method?
Answer : The choropleth method uses different shades of colors to show variations in a factor. It is easy to compare regions but does not show exact values. Sharp color boundaries may also be misleading.
4. How does the isopleth method help in studying climate?
Answer : The isopleth method connects places with the same value, like temperature or rainfall, using lines. If lines are close together, the change is fast; if they are far apart, the change is slow. This method is best for climate maps.
5. What are the steps to make a choropleth map?
Answer : First, collect data and divide it into classes (like population density levels). Then, use different shades of colors for each class. Finally, draw and label the map properly for easy understanding.
6. Why are distributional maps important for development?
Answer : Distributional maps help governments, businesses, and planners understand areas better. They are used for urban planning, disaster management, and agriculture. These maps also help in resource allocation.
7. What is a geographical field visit? How does it help in studying maps?
Answer : A field visit helps students understand geography by observing real places. It includes collecting data, taking photos, and talking to people. This practical experience improves map reading and geographical knowledge.
8. Compare the dot method and choropleth method.
Answer : The dot method uses dots to show values, while the choropleth method uses colors. Dots are better for counting things like population, while colors are better for showing density. Both methods help in geographical studies.
