2.2.2 Identify the perennial water source in block C 2 on the topographic map. (1×2) (2)

In block C2, the perennial water source can typically be identified by looking for blue lines or shapes indicated on the topographic map. These features represent rivers, streams, lakes, or ponds that maintain a constant water supply throughout various seasons, unlike temporary sources which may be marked differently. Additionally, when examining the contour lines surrounding these water features, a close cluster of lines can indicate valley areas where water naturally collects, further confirming the presence of a perennial water source. Always check the map legend for specific symbols used for water sources to ensure accurate identification!
