  1. Nepalis call Mount Everest Sagarmatha.
  2. Mining is a major activity on plateaus.
  3. The sudden fall of snow, ice or rocks from a mountainside is known as an avalanche.
  4. A piece or stretch of land, from the point of view of its physical features, is called terrain.
  5. A plant-like organism that generally clings to rocks, walls or trees is called lichen.

D. Match the following items in Column A with those in Column B:

Column AColumn B
1. The Aravalli Range(c) Older hills
2. The Victoria Falls(e) The Zambezi in southern Africa
3. The East African Plateau(d) Gold and diamond mining
4. A small green plant without flowers(a) Moss
5. The largest and highest plateau(b) Tibetan Plateau

E. Short Answer Questions:

  1. Mountains are called ‘storehouses of minerals’. Give reason with an example.
    Mountains and plateaus are called storehouses of minerals because they are rich in mineral resources. For example, the Aravalli Range is rich in minerals and mining activities are common in these regions.
  2. Why are the Aravalli Hills rounded at the top?
    The Aravalli Range is one of the oldest mountain ranges in the world. Over time, erosion by wind and water has made its peaks rounded.
  3. Name the rivers which originate in the Himalayas.
    Rivers like the Ganga, Yamuna, and Brahmaputra originate in the Himalayas.
  4. How are plateaus similar to mountains?
    Both plateaus and mountains are elevated landforms, formed due to tectonic movements. They may contain mineral deposits and have rugged terrain.

F. Long Answer Questions:

  1. Mining is a major activity on plateaus. Why? Explain with some examples.
    Plateaus are rich in minerals, making mining a major activity. For example, the Chhota Nagpur Plateau has reserves of coal, iron, and manganese. The East African Plateau is known for gold and diamond mining. The availability of minerals near the surface allows easy access for mining.
  2. How are mountains different from plateaus in terms of occupation, soil, environment, vegetation, and scenic beauty?
    • Occupation: In mountains, herding and tourism are common; in plateaus, mining is prevalent.
    • Soil: Mountain soil is thin and less fertile; plateau soil can vary but is often rocky. Lava plateaus may have fertile black soil.
    • Environment: Mountains have cold climates with high altitudes; plateaus have diverse climates.
    • Vegetation: Mountains have montane forests; plateaus have grasslands or sparse vegetation.
    • Scenic Beauty: Mountains are more scenic and attract more tourists due to their snow-capped peaks and valleys.

G. Assertion and Reason Questions:

  1. Assertion: Many plateaus have rocky soils.
    Reason: Less fertile plateaus are less favourable to farming.
    Answer: (a) Both Assertion and Reason are true and Reason is the correct explanation of Assertion.
  2. Assertion: Tourism is often an important source of income for the people living in the mountains.
    Reason: The crisp mountain air and scenic beauty attract tourists.
    Answer: (a) Both Assertion and Reason are true and Reason is the correct explanation of Assertion.
  3. Assertion: The mountain terrain is flat and smooth.
    Reason: In many mountainous regions of the world, agriculture is practised over herding.
    Answer: (d) Both Assertion and Reason are false.

H. Case Study Questions:

  1. What is an important source of income for the people living in the mountains?
    Tourism
  2. Name some important mountain sports.
    Skiing, hiking, mountaineering, paragliding
  3. Why did people travel to the mountains in the past?

  4. Name the first Indian woman to climb Mount Everest.
    Bachendri Pal
  5. How can you say that mountain environment is under pressure?
