Step-by-step explanation:
The predominant climates of South America are Tropical (Type A) and Temperate (Type C) climates.
Tropical climates are usually found in the tropics and have warm temperatures year-round with high precipitation. Type C climates are moderate in temperature and precipitation and are found mostly in the mid-latitudes bordering the tropics. Seasonal changes are pronounced, with distinct winters and summers.
Examples of Type C climates in South America include Uruguay, the Pampas region of Argentina, and central Chile, while the Atacama Desert and Patagonia have Type B (Dry or Arid) climates.
