Question

Q. Read the extracts and answer the question that follows:
The Ganga plain extends between Ghaggar and Teesta rivers. It is spread over the states of
North India, Haryana, Delhi, U.P., Bihar, partly Jharkhand and West Bengal to East,
particularly in Assam lies the Brahmaputra plain. The northern plains are generally described
as flat land with no variations in its relief. It is not true. These vast plains also have diverse
relief features. According to the variations in relief features, the Northern plains can be
divided into four regions. The rivers, after descending from the mountains deposit pebbles in
a narrow belt of about 8 to 16 km in width lying parallel to the slopes of the Shiwaliks. It is
known as Bhabar. All the streams disappear in this Bhabar belt. South of this belt, the streams
and rivers re-emerge and create a wet, swampy and marshy region known as terai. This was a
thickly forested region full of wildlife. The largest part of the northern plain is formed of older
alluvium. They lie above the flood plains of the rivers and present a terrace like a feature. This
part is known as Bhangar. The soil in this region contains calcareous deposits locally known
as Kankar. The newer, younger deposits of the flood plains are called khadar. They are
renewed almost every year and so are fertile, thus, ideal for intensive agriculture.
i)Which type of deposits are perfect for agriculture and why?
