12 Biomes The main characteristics of the desert biome Climate, soil type, flora and fauna of the desert biome

Desert biome Chapter 12: Biomes Arid region Little or no rain Low temperature: 15–30° mid temperature: 30–40° 10% sandy Some cold, e.g. Gobi Large diurnal temperature range Semi-arid, 250–500 mm

Climate Chapter 12: Biomes Trade winds Rain-shadow effect Influence of cold ocean currents Continentality

Soils Chapter 12: Biomes Characteristics Lack of vegetation Lack of rainfall Soil-forming factors

Flora Chapter 12: Biomes Life cycle Succulents Root systems Defensive systems

Fauna Chapter 12: Biomes Behaviour Body-form evolution Body-function evolution
