Answer 2

Answer:

The northern plain of India is formed by three river systems, i.e. the Indus, the Ganga and the Brahmaputra; along with their tributaries.

This plain is composed of alluvial soil which has been deposited over millions of years.

The total area of the northern plain is about 7 lakh square kilometer.

It is about 2400 km long.

Width is about 240 to 320 km .

Northern plains are most densely populated areas of the country.

Here we find alluvial soil, thus making the plain very fertile and agriculturally very productive.

Because of the three river systems, i.e. the Indus, the Ganga and the Brahmaputra; along with their tributaries, availability of water is there in abundance through the year.

The rivers in their lower course split into numerous channels or streams due to the deposition of silt. These channels or streams are known as Distributaries.

The northern plain is divided into three sections, i.e. the Punjab Plain, the Ganga Plain and the Brahmaputra Plain.
