4. The Equatorial Rainforest

5. Course Content Tropical Rain Forest  Location  Climate  Vegetation

6. Location of Tropical Rainforest Between 10 o N and 10 o S Amazon Basin Congo Basin South-east Asia

7. Climate of Rainfores High insolation Monthly temperature between 26 o C and 27 o C Annual rainfall usually more than 2000mm Convection Rain is common Hot and wet throughout the year

8. Temperature Chart

9. Reason of high temperature Warmer Cooler Sun Rays Longer Distance Shorter Distance

10. Rainfall Chart

11. Formation of Convection Rain Solar Radiation Evaporation Cumulonimbus Cloud

12. Photo of Convection Rain

13. General Characteristics of the vegetation Evergreen Dense and luxuriant Many species Four layers

14. Vegetation Structure Emergents LayerCanopy LayerMiddle Layer Shrub Layer and Understorey

15. Vegetation Layers  Emergent layer very tall tree few in number  Canopy layer a continuous cover  Middle layer younger trees  Shrub layer and undergrowth little growth because of shade

16. Vegetation Morphology Climbers Epiphytes Broad crown Tall, straight trunk Buttress roots Drip-tip leaves

17. Buttress root

18. Drip-tip leaves

19. Climber

20. Ephiphyte

21. Tall trunk and broad crown
