Final answer:
Rainforests, commonly found in tropical equatorial regions, are known for their stable temperatures, high rainfall, and year-round evergreen vegetation with broad leaves. They support high biodiversity and distinct vertical vegetation layering.
Step-by-step explanation:
To describe a forest as a rainforest, several weather factors are typically considered. Rainforests are characterized by their location, often found in tropical equatorial regions, and by their high biodiversity. They are distinguished by having high net primary productivity due to their warm and moist climate, which supports rapid plant growth year-round.
The climate of rainforests includes average temperatures ranging from 20°C to 34°C (68°F to 93°F), with little variation month-to-month, leading to continuous plant growth.
Additionally, rainforests receive a high amount of rainfall, usually leading to soils that are low in nutrients due to rapid leaching. Vegetation in rainforests is evergreen and characterized by plants with broad leaves that are replaced throughout the year. The tropical rainforests have distinct vertical layering of vegetation and a variety of habitats for different animal species.
