Contour Maps and Landforms
Short Questions
1. What is a contour map?
Answer: A contour map is a type of map that shows landforms and elevations using contour lines.
2. What do contour lines represent?
Answer: Contour lines represent places with the same altitude on a map.
3. How can we identify steep slopes on a contour map?
Answer: Steep slopes are identified where contour lines are very close to each other.
4. How can we identify gentle slopes on a contour map?
Answer: Gentle slopes are identified where contour lines are spaced far apart.
5. Why are contour maps useful for trekkers and mountaineers?
Answer: Contour maps help trekkers and mountaineers plan safe and easy routes.
6. What is the use of contour maps in farming?
Answer: Farmers use contour maps to plan irrigation and prevent soil erosion.
7. Do contour lines ever cross each other?
Answer: No, contour lines generally do not cross each other.
8. What is the purpose of contour intervals?
Answer: Contour intervals show the difference in height between two contour lines.
9. Who else finds contour maps useful besides farmers and trekkers?
Answer: Soldiers, defense officers, and planners find contour maps useful.
10. What do closer contour lines indicate about a mountain?
Answer: Closer contour lines indicate that the mountain has a steep slope.
Long Questions
1. How do contour maps help in planning for a region?
Answer: Contour maps help in understanding land features, water flow, and elevation, which is useful in city planning, road construction, and disaster management.
2. How do soldiers and defense officers use contour maps?
Answer: Soldiers and defense officers use contour maps for strategic planning, identifying safe routes, and setting up camps in high-altitude areas.
3. Why is it important for farmers to study land slopes?
Answer: Farmers need to study land slopes to plan irrigation systems, prevent soil erosion, and grow crops in areas best suited for agriculture.
4. How does a contour map differ from a normal map?
Answer: A contour map shows elevation and landforms using contour lines, while a normal map focuses on locations, roads, and political boundaries.
5. What happens when contour lines are evenly spaced on a map?
Answer: When contour lines are evenly spaced, they indicate a uniform slope, meaning the land rises or falls at a steady rate.
6. What kind of areas are best suited for agriculture based on contour maps?
Answer: Gently sloping or flat areas with well-spaced contour lines are best suited for agriculture as they allow better water retention and reduce erosion.
7. How can contour maps be helpful in constructing roads?
Answer: Engineers use contour maps to design roads that avoid steep climbs and landslides by selecting routes with gentle slopes.
8. Why is understanding contour lines important in flood-prone areas?
Answer: In flood-prone areas, contour maps help in identifying low-lying regions that are at risk, allowing authorities to take preventive measures.
9. What is the role of contour maps in environmental conservation?
Answer: Contour maps help in afforestation, water conservation, and preventing land degradation by showing which areas need soil and water conservation efforts.
10. How do contour maps help in predicting water flow in a region?
Answer: Contour maps indicate the direction of slope, helping in predicting how water will flow during rains, which is essential for drainage and flood control planning.
