Explanation
Natural vegetation in India is classified based on climatic conditions, primarily rainfall and temperature. Tropical Evergreen Forests are found in regions with heavy rainfall (over 200 cm) and high humidity, where trees remain green throughout the year. In contrast, Tropical Deciduous Forests (Monsoon Forests) are found in regions with rainfall between 70 cm and 200 cm, and trees shed their leaves for about six to eight weeks in dry summer.
