Chapter 03 : Landforms and Life

Question: What are landforms? How many categories can they be divided into?

Answer: Landforms are physical features on the Earth's surface that form over millions of years. They can be divided into three main categories:

  • Mountains (e.g., the Himalayas, the Andes)
  • Plateaus (e.g., the Tibetan Plateau, the Deccan Plateau)
  • Plains (e.g., the Gangetic Plain)

Question: What is the difference between mountains and hills?

Answer: Mountains are high, with sharp peaks and steep slopes. Hills are relatively low, with rounded peaks and gentle slopes.

Question: Why are plateaus called "storehouses of minerals"?

Answer: Plateaus contain abundant reserves of minerals (e.g., iron, coal, gold).

  • Chhota Nagpur Plateau (India) – iron ore and coal
  • East African Plateau – famous for gold and diamonds

Question: Why are plains best suited for agriculture?

Answer: Plains are made up of fertile sediment (silt) brought by rivers.

  • The soil is extremely fertile.
  • Irrigation and transportation are facilitated.
  • Example: The Gangetic plain produces rice and wheat abundantly.

Question: Name some of the world's major mountains.

Answer:

  • Mount Everest (Nepal/Tibet) – the world's highest peak.
  • Mount Kilimanjaro (Africa) – a single mountain.
  • Mount Kanchenjunga (India/Nepal) – second highest peak in Himalayas.
  • Anamudi – the highest mountain in South India

Question: Why is the Tibetan Plateau called the "Roof of the World"?

Answer: Because the Tibetan Plateau has an average elevation of 4500 meters above sea level, making it the world's highest plateau.

Question: What types of trees are found in mountain forests?

Answer: Mountain forests are home to coniferous trees (such as pines and firs) with thin needle-like leaves.


Question: NCERT - What landform is your town located on?

Answer: (Example based on observation)

  • Plains → fertile soil, rivers, flat land
  • Mountains → high peaks, slopes, coniferous forests
  • Plateau → rocky terrain, mineral wealth

Question: Describe three landforms from Chota Nagpur to Prayagraj to Almora.

Answer:

  • Chhota Nagpur – Plateau (rich in minerals)
  • Prayagraj – Plain (confluence of Ganga & Yamuna)
  • Almora – Mountain region (Himalayas)
