Class 11 Geography Chapter 5 Short Answer Questions

Q12. Why do tropical evergreen forests remain green throughout the year? How are they different from semi-evergreen forests?

Answer: Tropical evergreen forests grow in warm, humid regions with heavy rainfall. They remain green because trees do not shed their leaves at the same time.

• Rainfall: Evergreen forests receive more than 200 cm annually.

• Temperature: Mean annual temperatures generally exceed 22°C.

• Layers: Shrubs, creepers, shorter trees and tall trees form distinct layers.

• Height: Some trees reach 60 metres or more.

• Leaf shedding: Not all trees shed leaves simultaneously.

• Semi-evergreen: Found in relatively less rainy areas, with a mixture of evergreen and moist deciduous trees.

Conclusion: Semi-evergreen forests contain a greater mixture of trees with different leaf-shedding habits.

Q13. How do moist deciduous and dry deciduous forests differ in rainfall, distribution and tree species?

Answer: Tropical deciduous forests are the most widespread in India. They are divided according to water availability.

Conclusion: Moist deciduous forests receive more rain; dry deciduous forests transition towards thorn vegetation at drier margins.
