Short Answer Type Questions
Question 1. What are landforms and how many types are there?
Answer
Landforms are natural features of the Earth's surface, shaped over millions of years through processes like erosion and uplift.
- Examples include mountains, plateaus, and plains, each distinct in shape and formation.
- There are three primary types of landforms mentioned: mountains, which are elevated areas with high peaks; plateaus, which are elevated areas with flat tops; and plains, which are large stretches of flat land.
- Additionally, deserts are discussed as another type of landform characterized by their arid conditions.
Question 2. What are mountains and how do they differ from hills?
Answer
- Mountains are large landforms that rise prominently above their surroundings, typically having steep slopes, a pronounced summit, and a significant height above sea level. Examples include Mount Everest and Kanchenjunga. In contrast, hills are smaller and less steep than mountains, with more rounded tops.
- Mountains tend to have a more dramatic impact on the environment and climate than hills, and they usually feature more extreme biodiversity.
Question 3. What is terrace farming and why is it used in mountains?
Answer
Terrace farming involves the creation of stepped areas on mountain slopes for agriculture. This method is used in mountainous regions where the terrain is too steep for traditional farming.
- Terraces prevent erosion and surface runoff, maximizing water retention and allowing crops like rice and barley to be cultivated.
- This technique is essential in areas like North India, where flat land is scarce, making it a critical adaptation for sustaining agricultural productivity.

Question 4. What is a plateau and name two examples.
Answer
A plateau is an elevated area with a flat top and steep sides that rise sharply above surrounding land.
- Two examples mentioned are the Tibetan Plateau, referred to as the 'Roof of the World' due to its high elevation, and the Deccan Plateau in India, known for its rich volcanic soil.
- Plateaus are significant for their unique ecosystems and are often rich in minerals, making them important geographical features.
Question 5. Why are plateaus called ‘storehouses of minerals’?
Answer
Plateaus are often referred to as ‘storehouses of minerals’ because their geological formations typically contain abundant mineral deposits. For instance, the Chhota Nagpur Plateau in India is rich in iron, coal, and manganese, while the East African Plateau is known for its deposits of gold and diamonds. These highland areas provide valuable resources that are essential for industrial use, contributing significantly to local and global economies.

Question 6. What are plains and why are they good for agriculture?
Answer
Plains are broad, flat areas of land that generally have rich, fertile soil accumulated over time through the deposition of sediment by rivers and other geological processes.
- Their flatness and fertility make plains ideal for agriculture, allowing for extensive cultivation of crops such as grains, which require large, open spaces for optimal growth.
- Examples include the Ganga Plain, which is known for its productive agricultural land.
Question 7. What are deserts and how have humans adapted to them?
Answer
Deserts are arid regions with very little precipitation, making them inhospitable environments for most forms of life. Humans have adapted to these conditions through various means.
- For example, in the Thar Desert, communities have developed unique architectural styles that maximize cooling, and water conservation techniques that allow them to survive.
- Cultural adaptations include the development of nomadic lifestyles, which enable people to move in search of resources.
Question 8. What is snow and how does it affect mountain life?
Answer
Snow is water falling as a solid, forming a white blanket at high altitudes where it’s cold enough, unlike rain or hail in lower areas.
- In mountains like the Himalayas, snow covers peaks, melting in summer to feed rivers like the Ganga, supporting life. At higher altitudes, it stays permanent, making peaks snow-capped.
- This affects mountain life by limiting farming to valleys or terraces and attracting tourists for skiing, as in north India. Snow’s beauty and water supply make it vital, though it poses challenges like avalanches.
Question 9. Why are waterfalls common on plateaus?
Answer
Waterfalls are common on plateaus because their steep slopes and edges cause rivers to drop sharply, as seen with Nohkalikai Falls (340 m) on the Cherrapunji Plateau.
- Plateaus like the Deccan or Tibetan rise high with flat tops, and rivers flowing off these edges create spectacular falls, like Jog Falls in the Western Ghats. Volcanic plateaus with rocky terrain channel water into these drops.
- These falls add beauty, drawing tourists, and highlight plateaus’ unique geography compared to flat plains or peaked mountains.
