Chapter 6 Major Landforms of the Earth Short Answer Questions (SAQs):


1. Which are the two processes that lead to formation and development of landforms?

Answer

The two processes that lead to the formation of landforms are:
• Internal Process: This process leads to the upliftment and sinking of the earth’s surface at several places. Example: block mountains.
• External Process: The external process is the continuous wearing down and rebuilding of the land surface. Examples: Barchans.

2. How are Plains formed?

Answer

Plains are formed by the rivers. The rivers erode the slopes of mountains and carry forward the eroded material. They then deposit their load consisting of stones and sand along their courses and in valleys. In this way the plains are formed.

3. Why mountains are less populated?

Answer

The mountains are thinly populated because:
• Harsh climate is found in mountainous area that is not suitable for people.
• The mountain slopes are steep making it difficult to construct buildings.
• Less land is available for farming.

4. How do mountains change climate of a place?

Answer

Mountainous areas have lower temperatures. They serve as climatic divide between two adjoining regions. The Himalaya for example forms a barrier to the movement of cold winds from Central Asia towards the Indian subcontinent. They also force the South West Monsoons to ascend and cause rainfall on their southern slopes.

5. What are the various uses of plateaus?

Answer

• Plateaus are rich in mineral deposits
• Most of the India's mining area are located in plateau
• Plateau areas have plenty of waterfalls, scenic spots and are great attraction for tourist
• The lava plateaus are rich in black soil that is good and fertile for cultivation.

6. Write a short note on lava plateau.

Answer

Lava plateaus are formed by highly fluid basaltic lava during numerous successive eruptions through numerous vents without violent explosions. These eruptions are quiet because of low viscosity of lava and contains small amount of trapped gases. Multiple successive and extensive lava flows cover the original landscape to eventually form a plateau, which may contain lava fields, cinder cones, shield volcanoes and other volcanic landform.

7. How are volcanic mountains formed? Give few example of volcanic mountain.

Answer

Volcanic mountains are formed due to volcanic activity that is due to solidification of lava. Mt. Kilimanjaro in Africa and Mt. Fujiyama in Japan are examples of such mountains.

8. What do you mean by sedimentation?

Answer

Deposition, also known as sedimentation, is the geological process whereby material is added to a landform. This is the process by which wind, water or ice transport previously eroded sediment, which, at the loss of enough kinetic energy in the fluid, is deposited another geographical location.

9. How are mountains useful to man?

Answer

Mountains are useful to man in a variety of ways:
• The mountains are a storehouse of water. Many rivers have their source in the glaciers in the mountains. Reservoirs are made and water is harnessed for the use of people.
• Mountains have a rich variety of flora and fauna. The forests provide fuel, fodder, shelter and other products like gum , raisins, etc.
• Mountain provide an idyllic site for tourists. They visit the mountains for their scenic beauty.

10. What do you mean by block mountains? Give examples.
