1) India is a country of vast geographical expanse. The climate of a place is affected by its location, attitude, distance from the sea, and relief. Therefore, we experience regional differences in the climate of India
2) Jaisalmer and Bikaner in the desert of Rajasthan are very hot, while Drass and Kargil in Jammu and Kashmir are freezing cold. Coastal places like Mumbai and Kolkata experience moderate climate. They are neither too hot nor too cold.
3) Due to variation in geographical conditions in these regions, the lifestyle, food habits, culture, language etc of people living here too differ from each other
4) Though there is diversity in India, we find unity which binds us as one nation
