B.Answer the following questions briefly:-
Que-1What is the bhabar?
Ans. 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.
Que-2Distinguish Between Bhangar and Khadar?
Ans:Bhangar:
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 feature. This part is known as bhangar
Khadar: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.
Ques-3Distinguish Between the Western Ghats and the Eastern Ghats?
Ans:Western
Ghats:
The Western Ghats are higher than the Eastern Ghats. Their
average elevation is 900– 1600 metres as against 600 metres of the Eastern
Ghats. The Western Ghats cause orographic rain by facing the rain bearing moist
winds to rise along the western slopes of the Ghats. The Western Ghats are
known by different local names. The height of the Western Ghats progressively
increases from north to south.
Eastern Ghats:
The Eastern Ghats stretch from the Mahanadi Valley to the
Nigiris in the south. The Eastern Ghats are discontinuous and irregular and
dissected by rivers draining into the Bay of Bengal. Mahendragiri (1,501
metres) is the highest peak in the Eastern Ghats. Shevroy Hills and the Javadi
Hills are located to the southeast of the Eastern Ghats
Que-4Which
are the major physiographic divisions of India? Contrast the relief of the
Himalayan region with that of the Peninsular plateau.
Ans 4:The physical features of
India can be grouped under the following physiographic divisions:
The Himalayan Mountains
The Northern Plains
The Peninsular Plateau
The Indian Desert
The Coastal Plains
The Islands
Ques5 Write short notes on the following.(i) The Indian Desert,
(ii) The Central Highlands
Ans.5
i) The Indian Desert
The Indian desest lies towards the western margins of the Aravali Hills. It is
an undulating sandy plain covered with sand dunes. This region receives very
low rainfall below 150 mm per year. It has arid climate with low vegetation
cover. Streams appear during the rainy season. Soon after they disappear into
the sand as they do not have enough water to reach the sea. Luni is the only
large river in this region. Barchans (crescent-shaped dunes) cover larger areas
but longitudinal dunes become more promiment near the Indo-Pakistan boundary.
(ii) The Central
Highlands
The Peninsular plateau consists of two broad divisions, namely, the Central
Highlands and the Deccan Plateau. The part of the Peninsular plateau lying to
the north of the Narmada river covering a major area of the Malwa plateau is
known as the Central Highlands. The Vindhyan range is bounded by the Central
Highlands on the south and the Aravalis on the northwest. The further westward
extension gradually merges with the sandy and rocky desert of Rajasthan.
