Rainfall:
* Receives at least 80 inches (2,000 mm) of rain annually, with some regions receiving over 400 inches (10,000 mm).
* The rain is usually distributed evenly throughout the year, with no distinct dry season.
Humidity:
* The air is consistently humid, typically above 77% throughout the year.
* This high humidity is a result of the abundant rainfall and the dense vegetation that prevents evaporation.
Biodiversity:
* Rainforests are home to a vast array of plant and animal species, representing over 50% of all known life on Earth.
* This incredible biodiversity is due to the abundance of resources, the stable climate, and the complex ecological interactions within the rainforest ecosystem.
Other Key Features:
* Warm Temperatures: Rainforests are located in tropical and subtropical regions, with average temperatures ranging between 68-93°F (20-34°C) year-round.
* Layers of Vegetation: Rainforests have multiple layers of vegetation, from the towering canopy trees to the understory shrubs and the forest floor.
* Rapid Decomposition: The warm temperatures and high humidity promote rapid decomposition of organic matter, leading to nutrient-rich soil.
Types of Rainforests:
* Tropical rainforests: Located near the equator, characterized by warm temperatures and high rainfall year-round.
* Temperate rainforests: Found in cooler regions with high rainfall, typically along coastlines.
Rainforests play a vital role in regulating the global climate, providing essential ecosystem services, and serving as a haven for countless species. They are also important sources of medicinal plants, timber, and other resources. However, they are facing threats from deforestation, climate change, and other human activities.
