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.
