Question

Study the temperature and rainfall graph given in Fig. and answer the following questions.

1. Which place is represented by this graph?
2. Why annual range of temperature is large?
3. Why rainfall is meagre?

Answer 1

1. The graph represents a place in the north-western desert region, most likely Jaisalmer, Rajasthan.
2. The annual range of temperature is large because:
   • Jaisalmer is in a desert area (Thar Desert).
   • There are high summer temperatures (over 35°C) and low winter temperatures (below 10°C).
   • The absence of the moderating influence of the sea leads to extreme temperatures.
3. Rainfall is low because:
   • Jaisalmer is in the rain-shadow region of the Aravalli Hills.
   • The southwest monsoon winds lose most of their moisture before reaching this area.
   • The region lies in the Thar Desert, which is naturally dry.
