Tropical Rainforests and Deforestation

These flashcards cover key concepts related to tropical rainforests, their climates, structures, vegetation adaptations, the impacts of deforestation, and related socio-political issues.

Equatorial Climate

A warm, hot, and humid climate that exists year-round in tropical rainforest regions, characterized by minimal temperature range and high annual rainfall.

Convectional Rainfall

Rainfall caused by warm air rising in a low-pressure area, leading to cloud formation and precipitation.

Emergent Layer

The top layer of the rainforest where tall trees rise above the canopy, receiving the most sunlight.

Canopy Layer

The dense layer of leaves and branches formed by the tops of tall trees in a rainforest, where much of the biodiversity exists.

Understory Layer

The layer below the canopy where smaller trees and plants grow, receiving limited sunlight.

Drip Tips

Special leaf shapes that allow rainwater to run off quickly, preventing fungal growth and helping plants in humid environments.

Lianas

Long, woody vines that climb up trees to access sunlight in the rainforest.

Epiphytes

Plants that grow on other plants for support, often found in the canopy and absorbing moisture from the air.

Deforestation

The clearing or removal of forests or trees, often resulting in damage to the quality of the land.

Soil Erosion

The process by which the top layer of soil is removed due to natural factors like water and wind, often exacerbated by deforestation.

Biodiversity

The variety of life in a particular habitat or ecosystem, including the number of different species.

Hydroelectric Power (HEP)

Electricity generated by flowing water, commonly associated with large dams built in rainforest areas.

Mercury Pollution

Contamination of water bodies with mercury, often from gold mining, which poses health risks to humans and wildlife.

Carbon Dioxide Absorption

The process by which trees and plants take in carbon dioxide from the atmosphere, mitigating global warming.

Albedo Effect

The reflection of sunlight off surfaces; less forest means more heat is absorbed by the land, increasing local temperatures.

Conflict over Land Use

Disputes that arise between indigenous tribes and companies over the use and management of rainforest land.
