The Big Questions (Page 41)

Q1: What are the major types of landforms and their significance to life and culture?
Ans: The major types of landforms are mountains, plateaus, and plains.

• Mountains: These landforms are significant as they influence climate and weather patterns, provide habitats for diverse flora and fauna, and offer resources such as fresh water from melting snow. Mountains hold cultural significance in many regions, often considered sacred and are popular for tourism and recreational activities.
  
• Plateaus: Plateaus are known as storehouses of minerals and have varied climates and environments. They are important for mining activities and can support agriculture if the soil is fertile, particularly in volcanic regions with rich black soil. Plateaus also house spectacular waterfalls, adding to their scenic and economic value.
  
• Plains: Plains are vital for agriculture due to their fertile soils, which result from sediment deposits by rivers. They support large populations and are centers of human civilization, offering suitable conditions for farming, settlement, and transportation.
  

Q2: What are the challenges and opportunities of life associated with each landform?
Ans:

• Mountains:
  • Challenges: Harsh climates, difficulty in transportation, limited agricultural land, risk of natural disasters like avalanches and landslides.
    
  • Opportunities: Tourism, winter sports, mountaineering, cultural significance, water sources from glaciers and rivers.
    
• Plateaus:
  • Challenges: Less fertile soil compared to plains, rocky terrain, harsh climates in some regions.
    
  • Opportunities: Rich mineral deposits leading to mining activities, scenic waterfalls attracting tourism, unique flora and fauna.
    
• Plains:
  • Challenges: Risk of flooding, high population density leading to pollution and resource depletion, dependency on rainfall or irrigation for agriculture.
    
  • Opportunities: Fertile land for agriculture, suitable for large human settlements, easy transportation and trade routes, diverse economic activities like farming and fishing.
