All Flashcards
What factors define terrestrial biomes?
Plant life, temperature, and precipitation.
Why does the equator receive more solar energy?
Due to the Earth's tilt, the equator receives more direct sunlight.
How does climate influence biomes?
Climate, specifically temperature and precipitation, determines the distribution and characteristics of biomes.
Why are tropical rainforest soils nutrient-poor?
Rapid decomposition and high rainfall quickly cycle and leach nutrients.
What limits plant growth in savannas?
Warm temperatures promote decomposition, but dry climate limits plant growth.
What is the effect of permafrost melting?
Release of greenhouse gases, changes to landscape, and impacts on infrastructure.
What is the effect of deforestation in rainforests?
Loss of biodiversity, soil erosion, and climate change.
How does climate change affect biomes?
Shifts biome boundaries, alters species distribution, and increases extreme weather events.
What is a biome?
A large geographic area characterized by specific climate conditions and unique plant and animal communities.
What is permafrost?
Permanently frozen soil, characteristic of the tundra biome.
