INDIAN GEOGRAPHY

Detailed explanation-1: -The Northern Plain was formed by the interplay of the three major river systems, namely– the Indus, the Ganga and the Brahmaputra along with their tributaries. It is composed of alluvial soil which has been deposited over millions of years, it is about 2400 km long and about 240 to 320 km broad.

Detailed explanation-2: -The rivers originating from the Himalayas bring rich alluvial sediments down in the plains, creating the fertile alluvial soil.

Detailed explanation-3: -Most alluvial soils are derived from the sediment being deposited by the river Ganga in the Indo–Gangetic plain, ranging from Punjab in the west to West Bengal and Assam in the east, as well as in the coastal areas of northern parts of Gujarat, Narmada, and Tapi valleys, which are formed by sea waves.

Detailed explanation-4: -Alluvial soil is formed from the sediments deposited by the rivers in Indo-Gangetic plains and by sea waves in the coastal plains. It is very fertile and hence, excellent for agriculture. This soil is found extensively in the northern plains and other river valleys in India.

Detailed explanation-5: -The Northern Plains of India have been formed by the Ganga, the Indus and the Brahmaputra rivers and their tributaries. The northern part of the Indian Peninsula subsided due to the upliftment of the Himalayas in the Tethys sea and resulted in a large basin.
