This PPT is for students of GRADE 5,6,7 and above.The content available in this PPT is simple and basic for the initial understanding of different landforms of the earth.In the end part of the slid you will also find few activities which can reflect varied responses and participation from the pupils end.Thank You
4. PLATEAU
A plateau is a flat, elevated landform that
rises sharply above the surrounding area on
at least one side.
Plateaus occur on every continent and take
up a third of the Earths land
. They are one of the four major landforms,
along with mountains, plains, and hills
Example., The Antrim plateau in Northern
Ireland, The Deccan Plateau in India and the
Columbia Plateau in the United States
6. PLAIN AREA
PLAIN AREAS are large stretches of
flat land. They are, generally, not more
than 200 metres above mean sea
level.
Some plains are extremely level.
Others may be slightly rolling and
undulating[irregular]
7. HOW DO PLAIN
AREAS FORM?? Most of the plains are formed
by rivers and their tributaries.
At first, the rivers flow down the
slopes of mountains and
erode[WASH] them.
Secondly, they carry forward the
eroded[WASHED] material.
Then they deposit their load
consisting of stones, sand and
silt along their courses and in
their valleys.
It is from these deposits that
PLAINS are formed.
8. FEATURES OF A PLAIN AREA
Generally, plains are very
fertile. Construction of
transport network is easy.
Thus, these plains are very
thickly-populated regions of
the world.
Some of the largest plains
made by the rivers are found
in Asia and North America. For
example, in Asia, these plains
are formed by the Ganga and
the Brahmaputra in India and
the Yangtze in China.
9. FEATURES OF A PLAIN AREA
Plains are the most useful
areas for human habitation.
There is great concentration
of people as more flat land
is available for building
houses, as well as for
cultivation.
Because of fertile soils, the
land is highly productive for
cultivation. In India too,
the Indo-Gangetic plains are
the most densely populated
regions of the country.
10. ACTIVITY
1. IDENTIFY THE TYPE OF
MOUNTAIN??
2. IDENTIFY WHICH MOUNTAIN IS
BEING FORMED BY THIS PROCESS??
11. How are plains formed?
A. By rivers and their tributaries
B. By the process Erosion and Deposition
C. Both A and B
12. Why are the river plains thickly
populated?
A. Since the landscape is beautiful
B. Since the land is very fertile
C. Both are incorrect
14. LANDFORMS AND THE PEOPLE
• Humans have been living on different kinds of
landforms in different ways.
• Life is difficult in mountainous areas whereas
Plains provide much better conditions. It is
easy to grow crops, build a house or road in a
plain than a mountain.
• Now can you point out some differences in
the ways people live on different kinds of
landforms?
15. HOW DO YOU USE YOUR LAND??
WATER POLLUTION-A CRY ECO FRIENDLY MEASURES
17. NATURAL
CALAMITIES
Sometimes, natural calamities such
as earthquakes, volcanic eruption,
storms and floods cause widespread
destruction.
Huge loss of life and property takes
place.
But by creative awareness about
such incidences we may lower the
risks.
