Why do you think water is scarce in the desert?
Answer:
Water is scarce in the desert because:
- Deserts receive very little rainfall throughout the year
- The sandy soil doesn’t retain water well as it quickly seeps deep into the ground
- High temperatures cause rapid evaporation of any surface water
- There are few rivers or natural water bodies in desert regions
- Groundwater is often found very deep below the surface

Look at the picture above and write your observations.
1. What type of animals do you see in the picture?
Answer:
In the mountain picture, we can see animals like yaks, mountain goats and birds adapted to mountain life.
2. How are the dresses worn by people living in the mountains different from those worn in your region?
Answer:
People in mountain regions like Sikkim wear warm, woolen clothing such as bakhu (traditional Sikkimese dress), dumdyam and Gunyo cholo. These clothes are thicker, often layered and designed to protect from cold weather. They are different from clothing in plains that is typically made of lighter cotton materials suitable for warmer climates.
3. Describe the trees found in the mountains.
Answer:
Mountain regions have trees like oak, pine, walnut, and chestnut. These trees have needle-shaped leaves (conifers), are evergreen, grow tall and straight, have strong roots to anchor in steep slopes and can withstand cold temperatures and snowfall. Their conical shape helps shed snow easily.
Page 147 – Discuss
1. How does the cold climate in mountain regions affect the way people live and dress?
Answer:
The cold climate in mountain regions affects people’s lifestyle by:
- Making them wear thick, woolen, layered clothing like bakhu and dumdyam
- Requiring houses built with wood and slanting roofs to shed snow
- Influencing their diet to include hot foods like thukpa to keep warm
- Using animals like yaks that can survive in cold conditions
- Developing festivals that celebrate the harsh climate and seasons
- Creating storage methods for food during heavy snowfall periods
2. What traditional clothes are worn in your region? How do they match with the local climate?
Answer:
Traditional clothes in plains regions include cotton kurta-pajama, sarees, and salwar kameez. These light, breathable fabrics are perfect for the hot and humid climate, allowing air circulation and sweat absorption. During winter, people add woolen shawls and sweaters for warmth.
3. Why do you think certain trees, like pine and oak, grow better in the mountains?
Answer:
Pine and oak trees grow better in mountains because:
- They have evolved to withstand cold temperatures and snowfall
- Their needle-shaped leaves minimize water loss in dry mountain air
- The conical shape helps snow slide off easily, preventing branch breakage
- They have strong root systems to anchor in steep mountain slopes
- They can photosynthesize even during short growing seasons
- They’re adapted to the thin, rocky soil found in mountain regions
4. How do animals like yak survive in the cold climate of Sikkim?
Answer:
Yaks survive in cold mountain climates through adaptations like:
โข Thick, woolly coats that provide insulation against extreme cold
โข Long hair that covers their bodies, including their legs
โข A compact body shape that conserves heat
โข Strong hooves that can navigate rocky, snowy terrain
โข The ability to digest tough mountain vegetation that other animals cannot eat
โข Special blood circulation that allows them to thrive at high altitudes with less oxygen
โข The ability to lower their metabolic rate during harsh winter months

1. Why do you think traditional houses in Sikkim are built with wood and have slanting roofs?
Answer:
Traditional houses in Sikkim are built with wood and have slanting roofs because:
- Wood provides better insulation against cold compared to stone or brick
- Slanting roofs help snow and rainwater slide off easily, preventing accumulation and roof collapse
- Wood is flexible and can withstand minor earth tremors common in mountain regions
- These materials are locally available in forest-rich mountain areas
- The design helps maintain warmth inside during cold weather
- Elevated wooden structures help protect from dampness and small animals
2. Does your house have any feature that is similar to the houses in the mountains?
Answer:
My house has a sloping roof similar to mountain houses, which helps during monsoon season to drain rainwater quickly. We also have wooden windows that provide good insulation, similar to mountain homes.
3. Why are landslides common in mountains during the rainy season?
Answer:
Landslides are common in mountains during the rainy season because:
- Heavy rainfall saturates the soil, making it heavier and unstable
- Water seeps between rocks and soil layers, creating slippery surfaces
- Steep slopes become more vulnerable when wet
- Water can erode the base of slopes, removing support for the land above
- Deforestation reduces the root systems that would otherwise hold soil in place
- Construction activities can destabilize natural slopes
4. What do you think can be done to keep people safe during the landslides?
Answer:
To keep people safe during landslides:
- Early warning systems can alert communities before landslides happen
- Building stronger retaining walls to hold back unstable slopes
- Planting trees with deep roots to hold soil in place
- Constructing houses away from landslide-prone areas
- Creating evacuation plans and emergency shelters
- Building proper drainage systems to channel rainwater safely
- Regular monitoring of high-risk areas during rainy seasons
- Educating communities about warning signs of impending landslides
5. What can communities do to help people who lose their homes or get affected by natural disasters?
Answer:
Communities can help people affected by natural disasters by:
- Setting up temporary shelters for those who lost homes
- Organizing collection drives for food, clothes and essential supplies
- Providing medical assistance to injured people
- Creating community funds to help rebuild homes
- Offering emotional support and counseling services
