Tropical Zone (Tropics)
Degree:
Characteristics:
Common Environments:
Examples:
Degree: between 0° and 23.5° north and south (23.5° N and S of Equator)
Characteristics: Hot all year (lot of sunlight), High Rainfall,
Common Environments: Rainforests, Monsoon regions
Examples: Congo and SE Asia
Subtropical Zone (Subtropical belt)
Degree:
Characteristics:
Examples:
Degree: Between 23.5° and around 35° N and S
Characteristics: Still warm/hot, drier than tropics, most of the worlds desert
Examples: Sahara Desert, South USA, some parts of Aus
Temperate Zone
Degree:
Characteristics:
Common Environments:
Examples:
Degree: From about 35° to 60° N & S
Characteristics: Experiences the 4 seasons, moderate temp/rainfall,
Common Environments: Forests, Grassland, Farmland
Examples: Most of Europe and USA, China, southern Australia,
Polar Zone
Degree:
Characteristics:
Examples:
Degree: From 60° to 90° north and south
Characteristics: Very cold, long and freezing winters, short and cold summers
Examples: Antarctica, Arctic, northern Canada and Russia
