Asia: Climate, Natural Vegetation and Wildlife — Question 10
Back to all questionsCactus
Key Concepts Covered
This question tests your understanding of the following concepts from the chapter Asia: Climate, Natural Vegetation and Wildlife: Question, Trees, Mainly, Found, Thorny, Vegetation. These are fundamental topics in Geography that students are expected to master as part of the ICSE Class 8 curriculum.
A thorough understanding of these concepts will help you answer similar questions confidently in your ICSE examinations. These topics are frequently tested in both objective and subjective sections of Geography papers. We recommend revising the relevant section of your textbook alongside practising these solved examples to build a strong foundation.

Read the question carefully and identify what is being asked. Break down complex questions into smaller parts. Use the terminology and concepts discussed in this chapter. Structure your answer logically — begin with a definition or key statement, then provide supporting details. Review your answer to ensure it addresses all parts of the question completely.
Key Points to Remember
- Reference specific locations, latitudes, or regions in your answers.
- Explain both physical and human factors where applicable.
- Use map references and diagrams to strengthen answers.
- Link geographic concepts to current real-world examples.

(Evergreen, Moist Deciduous, Dry Deciduous, Thorn, Mountain) — in decreasing order of rainfall
| Type | Rainfall | Key Trees | Where in India |
|---|---|---|---|
| Tropical Evergreen | >200 cm | Mahogany, ebony, rosewood | Western Ghats, NE India, Andaman |
| Moist Deciduous | 100–200 cm | Teak, sal, bamboo | Eastern Western Ghats, NE plains |
| Dry Deciduous | 70–100 cm | Neem, peepal, palas | Central India |
| Thorn & Scrub | <75 cm | Babool, cactus, khejri | Rajasthan, Gujarat |
| Mangrove | Coastal tidal | Sundari, rhizophora | Sundarbans, Gujarat coast |
| Mountain/Alpine | Varies | Deodar, pine, fir | Himalayas |
Himalayan Vegetation Zones
As you go UP the Himalayas, vegetation changes:
- Up to 1000 m: Tropical Deciduous (teak, sal)
- 1000–2000 m: Wet Temperate (oak, chestnut)
- 2000–3000 m: Coniferous (deodar, pine, fir)
- 3000–4000 m: Alpine Meadows (grasses, flowers)
- Above 4000 m: Tundra → permanent snow
Conservation Quick Facts
| Protected Area | State | Famous For |
|---|---|---|
| Jim Corbett NP | Uttarakhand | First national park (1936); Bengal Tiger |
| Kaziranga NP | Assam | One-horned Rhinoceros |
| Gir NP | Gujarat | Only home of Asiatic Lion |
| Sundarbans NP | West Bengal | Royal Bengal Tiger; largest mangrove |
Key Conservation Movements
- Chipko Movement (1973): Uttarakhand; villagers hugged trees to prevent cutting
- Van Mahotsav: Tree planting festival in first week of July every year
- Project Tiger (1973): Launched to protect Bengal tigers
Test Yourself
- Why do evergreen forests remain green throughout the year? Answer: Because they receive over 200 cm rainfall and trees shed leaves at different times (not all at once), so the forest always appears green.
- What are pneumatophores? Answer: Breathing roots of mangrove trees that stick up above the waterlogged soil to absorb oxygen.
- Why are deciduous forests commercially more important than evergreen forests? Answer: Because they have fewer species mixed together, making it easier to harvest commercially valuable trees like teak and sal.
- What percentage of India should be under forests according to the National Forest Policy? Answer: 33%
