1. Name the type of climate experienced by each place.
2. Describe the main features of the climatic type named above as experienced in India.
3. Which one of the places is inland and which one is coastal in location? How did you find out with the help of the data?
4. Why does the Tamil Coast receive rainfall during winters.

Answer 1

1. 
   
   1. Place A: Continental (Inland) Climate
   2. Place B: Coastal Climate
2. 
   
   1. Continental (Inland) Climate – Place A:
      • Wide temperature range: 12°C in January to 39°C in June.
      • Low winter rainfall, with high rainfall in monsoon months (June to September).
      • Typical of interior regions like Delhi or Nagpur, which are far from the sea.
   2. Coastal Climate – Place B:
      • Narrow temperature range: 24°C to 30°C throughout the year.
      • Heavy rainfall in monsoon (June to September), with some rain in winter months too.
      • Typical of coastal areas like Mumbai or Chennai, with influence of the sea moderating temperature.
3. 
   
   1. Place A is Inland:
      • High summer temperature (39°C) and low winter temperature (12°C) show large temperature variation, typical of inland areas.
      • Less humidity and rain outside monsoon season.
   2. Place B is Coastal:
      • Temperature remains steady (24°C–30°C), showing little variation due to the sea’s moderating effect.
      • High humidity and rainfall, including in winter months.
4. The Tamil Coast receives rainfall during winter (October to December) because of the North-East Monsoon. These winds blow from land to sea but pick up moisture from the Bay of Bengal, and when they hit the Eastern Ghats and Tamil Nadu coast, they cause rainfall. This is also called the retreating monsoon season.
