1.	Explain the origin, progress and retreat of the indian monsoon and discuss its impact on the indian economy.
Answer» Besides the monsoons, the INDIAN climate is INFLUENCED substantially by two more factors. The Himalayas contribute a continental nature to the climate, recognised by land WINDS, dry air, large diurnal range and scanty rainfall. The Indian Ocean, on the other hand, contributes a tropical character to the Indian climate characterised by uniformity of temperature throughout the year, short diurnal range, damp air, and frequent rainfall. The monsoon system of the Indian subcontinent differs considerably from that of the rest of Asia. The centres of action, air masses involved, and the mechanism of precipitation of the Indian monsoon are altogether different from other monsoon systems. Classical Theory or Thermal Concept of Indian Monsoons: According to this theory, the differential heating of land and SEA at the time when the sun makes an apparent northward movement is the main CAUSE of the Indian monsoonal regime.
