OUR COUNTRY – INDIA
India is a country of vast geographical expanse. In the
north, it is bound by the lofty Himalayas. The Arabian
Sea in the west, the Bay of Bengal in the east and the
Indian Ocean in the south, wash the shores of the
Indian peninsula.
India has an area of about 3.28 million sq. km. The
north-south extent from Ladakh to Kanyakumari is
about 3,200 km. And the east-west extent from
Arunachal Pradesh to Kuchchh is about 2,900 km.
The lofty mountains, the Great Indian Desert, the
Northern Plains, the uneven plateau surface and the
coasts and islands present a diversity of landforms.
There is a great variety in the climate, vegetation,
wildlife as well as in the language and culture. In this
diversity, we find unity that is reflected in traditions
that bind us as one nation. India has a population of
more than one hundred twenty crores since the
year 2011. It is the second most populous country of
the world after China.

States and 8 Union Territories (Appendix-I). Delhi is
the national capital. The states have been formed
mainly on the basis of languages.
PHYSICAL DIVISIONS
India is marked by a diversity of physical features such
as mountains, plateaus, plains, coasts and islands.
Standing as sentinels in the north are the lofty snow-
capped Himalayas. Him+alaya mean ‘the abode of
snow’. The Himalayan mountains are divided into three
main parallel ranges. The northernmost is the Great
Himalaya or Himadri. The world’s highest peaks are
located in this range. Middle Himalaya or Himachal
lies to the south of Himadri. Many popular hill stations
are situated here. Find out the names of five hill
stations. The Shiwalik is the southernmost range.
The Northern Indian plains lie to the south of the
Himalayas. They are generally level and flat. These
are formed by the alluvial deposits laid down by the
rivers– the Indus, the Ganga, the Brahmaputra and
their tributaries. These river plains  provide fertile land
for cultivation. That is the reason for high
concentration of population in these plains.
In the western part of India lies the Great Indian
desert. It is a dry, hot and sandy stretch of land. It
has very little vegetation.
To the south of northern plains lies the Peninsular
plateau. It is triangular in shape. The relief is highly
uneven. This is a region with numerous hill ranges
and valleys. Aravali hills, one of the oldest ranges of
the world, border it on the north-west side. The
Vindhyas and the Satpuras are the important ranges.
The rivers Narmada and Tapi flow through these
ranges. These are west-flowing rivers that drain into
the Arabian Sea. The Western Ghats or Sahyadris
border the plateau in the west and the Eastern Ghats
provide the eastern boundary. While the Western Ghats
are almost continuous, the Eastern Ghats are broken
and uneven (Figure 6.3). The plateau is rich in minerals
like coal and iron-ore.
To the West of the Western Ghats and the East of
Eastern Ghats lie the Coastal plains. The western
Alluvial deposits : These
are very fine soils,
brought by rivers and
deposited in the river
basins.
Tributary : A river or
stream which contributes
its water to a main river
by discharging it into
main river from either
side.
