India and the World: Land and the People
Introduction
Humans, like most mammals, live on land. Land, as you may
have noticed, has many forms and features; its appearance
changes a lot from one region to another. Suppose that you
are travelling by road from the region known as Chhota
Nagpur in Jharkhand, reach Prayagraj in Uttar Pradesh,
and go on to Almora in Uttarakhand. On the way, you will
see very different landscapes. In fact, you will encounter
three major landforms, which we will now explore.
LET’S EXPLORE
Æ As a class activity, form groups of four or five students
and observe the school’s surroundings. What kind of
landscape do you see? Will the landscape change a few
kilometres away? Or within some 50 kilometres? Compare
with other groups.
Æ In the same groups, discuss a journey that any of you
has made through a region of India. List the different
landscapes seen on the way. Compare with other groups.
A landform is a physical feature on the surface of our
planet Earth. Landforms take shape over millions of years
and have a significant connection with the environment
and life. They can broadly be divided into three categories
— mountains, plateaus and plains (Fig. 3.1).
These landforms have different climates and are home to
a variety of flora and fauna. Humans have adapted to all
landforms, but the number of people living on different
kinds of landforms varies throughout the world.
Mountains
Mountains are landforms that are much higher than the
surrounding landscape. They can be recognised by a broad
base, steep slopes and a narrow summit. Depending on
their height, some mountains are covered with snow. At
lower altitudes, the snow melts every summer and turns

may never melt, leaving the mountain permanently snow-
capped.
Other highlands with a lower height, less steep slopes and
rounded tops are called hills.
THINK ABOUT IT
What is snow? Unless you live in a Himalayan region (such
as Kashmir, Ladakh, Himachal Pradesh, Uttarakhand,
Sikkim, Arunachal Pradesh), you may never have seen
snow! In the rest of India, most precipitation is in the form
of rain and hail. But at higher altitudes, if it is cold enough,
snow will fall, covering the landscape in a soft and beautiful
white blanket. Snow and hailstones are nothing but
precipitation of water in a solid state.

Most of the world’s mountains are grouped in mountain
ranges, such as the Himalayas in Asia, the Alps in Europe
and the Andes in South America. Some of these ranges
stretch for thousands of kilometres.
Fig. 3.3. A sketch showing the relative heights of six mountains of the world
Fig. 3.2 shows pictures of six mountains of the world.
Fig. 3.3 brings them together to give a visual impression of
their relative heights from top to bottom. Mount Everest
(between Tibet (China) and Nepal) and Kanchenjunga
(between Nepal and the Indian state of Sikkim) are the two
highest peaks of the Himalayan range. Mount Aconcagua
(in South America) is the highest peak of the Andes. Mount
Kilimanjaro in eastern Africa is an isolated mountain that
is not part of any range. Mont Blanc in Western Europe
is the highest mountain of the Alps. Anamudi (in Kerala,
also known as ‘Anai Peak’) is the highest mountain in south
India.
