Chapter Analysis
Intermediate17 pages • EnglishQuick Summary
The chapter, 'Topographical Maps', in the Class 11 Geography textbook, covers the methods of representation and interpretation of relief features on maps. It discusses the use of contours, conventional signs, and symbols in topographic sheets, which are used globally for uniformity. The chapter explains how to interpret different geographic features like hills, valleys, plateaus, drainage patterns, and human settlements using these maps. Additionally, it elaborates on understanding cultural features such as settlements and transport networks from topographical sheets.

Additional Practice Questions
Explain the significance of contour intervals in topographic maps.
mediumAnswer: Contour intervals indicate the difference in elevation between two successive contour lines, providing insight into the steepness or gentleness of the terrain.
How can a topographic map be used to identify the transportation network in a region?
easyAnswer: Transport networks in a topographic map are identified using conventional symbols, showing roads, railways, and paths connecting different settlements, indicating accessibility and connectivity.
Discuss the importance of topographical maps in disaster management.
hardAnswer: Topographical maps are crucial in disaster management as they provide detailed information about terrain, helping in strategizing evacuation routes and identifying safe areas.
What is the role of 'legend' in topographical maps?
easyAnswer: The legend provides explanations of the conventional signs and symbols used, allowing the reader to understand and interpret map features accurately.
Compare and contrast V-shaped and U-shaped valleys using topographic maps.
mediumAnswer: V-shaped valleys on topographic maps are indicated by closely spaced contours forming a 'V' pattern, suggesting river erosion, while U-shaped valleys have wider spaced contours, indicating glacial erosion.
