Climate determines the distribution of large-scale ecosystems 5 of 18 What weather conditions are associated with low-pressure areas? Cloud and precipitation are associated with low-pressure areas. Dry weather is associated with high pressure. 6 of 18 What weather conditions are associated with high-pressure areas? Dry and warm weather conditions are associated with high -pressure areas. 7 of 18 What large-scale ecosystem would you expect to find at the Equator? Tropical rainforests are found at the Equator 8 of 18 What large-scale ecosystem would you expect to find 30°N and 30°S of the Equator? Deserts are found 30°N and 30°S of the Equator. 9 of 18 What is a biome? A biome is a large-scale ecosystem.

The main causes of desertification are population growth, removal of wood, soil erosion, overgrazing and climate change 17 of 18 Where are cold environments located?
