Question

Difficulty: EasySoils, Natural Vegetation, and Agriculture in India

Arrange the following types of natural vegetation found in India in increasing order of the average annual rainfall required for their growth:

  1. 1Tropical Thorn Forests
  2. 2Tropical Dry Deciduous Forests
  3. 3Tropical Moist Deciduous Forests
  4. 4Tropical Wet Evergreen Forests

Answer

The correct sequence of vegetation types in increasing order of annual rainfall requirement is: Tropical Thorn Forests (< 70 cm) → Tropical Dry Deciduous Forests (70 to 100 cm) → Tropical Moist Deciduous Forests (100 to 200 cm) → Tropical Wet Evergreen Forests (> 200 cm).
The natural vegetation in India varies according to precipitation levels. The correct sequence from lowest to highest annual rainfall requirement is: Tropical Thorn Forests (less than 70 cm), Tropical Dry Deciduous Forests (70–100 cm), Tropical Moist Deciduous Forests (100–200 cm), and Tropical Wet Evergreen Forests (more than 200 cm).

Step-by-Step Solution

1
Determine the rainfall range for Tropical Thorn Forests.
Tropical Thorn Forests develop in dry regions receiving less than 70 cm of annual rainfall.
Low moisture availability restricts vegetation growth to thorny trees and shrubs.
2
Determine the rainfall range for Tropical Dry Deciduous Forests.
Tropical Dry Deciduous Forests occupy regions receiving between 70 cm and 100 cm of rainfall.
This forms a transition zone between semi-arid thorn forests and moist deciduous forests.
3
Determine the rainfall range for Tropical Moist Deciduous Forests.
Tropical Moist Deciduous Forests flourish in areas with an annual rainfall of 100 cm to 200 cm.
Moderate rainfall allows trees to retain leaves for a longer period during monsoon months.
4
Determine the rainfall range for Tropical Wet Evergreen Forests.
Tropical Wet Evergreen Forests require high annual rainfall exceeding 200 cm.
Abundant moisture throughout the year supports dense, evergreen forest cover.
