World climate zones

你需要知道的

• World climates are grouped into zones that run roughly with latitude, because the Sun heats the equator more strongly than the poles.
• Rising warm air and sinking cool air help set where the wet and dry belts fall.
• Tropical zones stay hot, with heavy rain near the equator and deserts beside them. Temperate zones have warm summers and cold winters.
• Polar zones are cold and dry, with very long summer days and very long winter nights, and little plant growth.
