- Battle For The Biosphere
- Factors affecting Biomes
- Temperature and Precipitation
- In tropics suns rays concentrated over small area so veg grows well. Dense near equator. Polar areas rays less intense so veg growth is restricted.
- Where air rises in low pressure belts this leads to precicipation which gives rainforests
- Altitude
- Height of land, as temperature decreases 1 dc every 100m
- Continentality
- Distance from the sea as it keeps places cooler in summer & warmer in winter
- Soils
- Rich in nutrients will encourage growth of eco-systems
