Why moinsoon is known as unifying …

India is a vast country with varied topography. On the north the Himalayas protect the sub-continent from the extreme cold winds of Central Asia. This enables northern India to have uniformly higher temperatures as compared to other areas on the same latitudes. Similarly the peninsular plateau, under the influence of sea from three sides, has moderate temperatures. Despite such moderating influences there are great variations in the temperature conditions. 
Nevertheless, the unifying influence of the monsoons on the Indian subcontinent is quite perceptible. The Indian landscape, its animal and plant life, the agriculture calendar and the life of the people including their festivities and economic conditions revolve around the monsoon. Year after year, the people of India from North to South and from East to West eagerly await the arrival of the monsoon. These monsoon winds bind the whole country by providing water to set the agricultural activities. Thus, in view of the above the monsoon is considered as a unifying bond for this subcontinent.
