## 2. **Climate and Biomes**
South America’s **latitudinal extent** and varied topography create diverse climate zones:
– **Tropical Wet (Amazon)**: High rainfall and humidity sustain rainforests.
– **Savanna (Cerrado)**: Seasonal climates dominate central Brazil.
– **Desert (Atacama)**: Extreme aridity due to rain shadow effects.
– **Mediterranean (Central Chile)**: Mild, wet winters and dry summers.
– **Highland Climates (Andes)**: Vertical zonation affects agriculture and habitats.
