IB ESS HL 2.4.3 Biome Distribution Determinants Questions

Use temperature, rainfall, insolation and spatial data to explain biome distribution, vegetation and productivity.

Exam points

identify temperature, rainfall, insolation and other abiotic factors from biome, climate and map evidence
explain the distribution of a named biome by linking temperature, precipitation, hydrological conditions or atmospheric circulation to its location
compare named biomes using climate, abiotic conditions and resulting vegetation or biodiversity patterns
explain how abiotic conditions limit or support relative primary productivity and vegetation type
interpret spatial relationships in environmental data, such as altitude–cloud frequency or climate–vegetation patterns
