Question

State how rainfall and temperature influence the vegetation type in India.

Answer 1

Rainfall and temperature influence the vegetation to a great extent. In India, regions receiving rainfall over 200 cm with high temperatures have the tropical evergreen type of vegetation commonly. Regions with an average temperature of 24° C 27°C and rainfall ranging between 150 cm 200 cm have tropical deciduous forests. Regions with moderate rain of 50 cm have thorn and scrub type of vegetation.

Answer 2

• Rainfall Influence:
  • High Rainfall Areas (above 200 cm/year): Support Tropical Evergreen Forests with dense and diverse tree species (e.g., Western Ghats, Northeastern states).
  • Moderate Rainfall Areas (100–200 cm/year): Support Tropical Deciduous Forests, where trees shed leaves during dry seasons (e.g., Central India, Eastern Ghats).
  • Low Rainfall Areas (below 50 cm/year): Support Thorn and Scrub Forests, with drought-resistant plants like acacia and cacti (e.g., Rajasthan).
• Temperature Influence:
  • Warm Tropical Climate: Favors evergreen and deciduous forests, depending on rainfall.
  • Cooler Temperatures at High Altitudes: Lead to Mountain Forests, which vary from temperate forests to alpine vegetation with elevation.
