How northern plains differ from the rest of formation of land
Answers
The great Indian plain lies in the front of the Himalayas which are spread over an area of 777000kms. They include the Sindh plains, the Punjab Haryana plains, the desert of Rajasthan,the Ganga plain of uttar pradesh Bihar and west Bengal and the Brahmputra valley of Assam.It is also known as the great Northern plain of India. The plain is classical example of aggravational plain which resulted former an infilling of initial depression by incessant work of the Himalayan rivers. The maximum depth recorded so far is about 2000m .
Major characteristics :
The northern plain of India is one of the largest and most fertile plain has been formed by the alluvium brought down by Ganga,lndus,Yamuna,Ghaghara and their tributaries parallel to them.
The land is generally flattish as is evident from the variation in local relief that is only from 4 to 6 meters.
The general slope of the land is from North to south but there are many micro slopes. The intervening slopes which are quite pronounced with the relative variations of 15 to 30m in relief are locally known as khols.
The Ganga Yamuna doab is the largest doab(the alluvial land between two converging rivers, esp the area between the Ganges and Jumna in N India).
Most of the part of Northern plain is traversed by rivers. The north Bihar plain is known as land of rivers.
At some places a long marshes extendes like from Chapra to Khagaria a long narrow marshes parallel to Ganga ,locally known as the Caurs.
The most important characteristics is that watertable in this region is very high and the quality of water is also very good.
The plain is narrowest in Askam where it is only 90–100kms. Wide but it widens to a maximum of 400kms. in Bengal; it expands to about 500kms. in West end India and the adjoining Pakistan region.
The plain has its own diversity. The plain is recognised as consisting of four division each characterised by important differences is surface relief. They are the Bhabhar, Tarai, Bhangar and the khadar.
There are two main features on the Indian plain - alluvial cones and fans and interconnect.
