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 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.
How does deforestation affect tropical rainforests?
Leads to habitat loss, decreased biodiversity, and soil erosion.
How does climate change impact the tundra?
Causes permafrost to melt, releasing greenhouse gases and altering the landscape.
