Short Answer Type Questions

Question. 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. 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. 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. 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. 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.
