Major landforms of the earth

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

1. MAJOR LANDFORMS OF THE EARTH

2. MOUNTAINS BLOCK MOUNTAIN FOLD MOUNTAIN

3. VOLCANIC MOUNTAIN

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

5. PLAIN

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 ? By rivers and their tributaries By the process Erosion and Deposition Both A and B

12. Why are the river plains thickly populated? Since the landscape is beautiful Since the land is very fertile Both are incorrect

13. THANK YOU!! HOPE YOU ENJOYED THIS PRESENTATION??

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

16. A OR D ?? DEFORESTRATION AFFORESTRATION

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.

18. NATURAL CALAMITIES TROPICAL STORM OR TSUNAMIS VOLCANIC ERUPTION
