How can the climate of a place be inferred from the topo-sheet?
Answer
The climate of a place can be inferred from the latitudinal extent of the area covered by the toposheet and the type of natural vegetation found there.
- The latitude indicates whether the climate is hot, temperate, or cold. For example, places near 10° N are generally warmer than places near 35° N.
- The vegetation also indicates the climate. Dense forests suggest heavy rainfall, while cactus, thorny bushes, and sparse grasses indicate an arid or semi-arid climate.
