Describe the type of b

Contains much of the world's terrestrial biodiversity, including insects, birds, and mammals.

Biodiversity

Dominated by trees, which is around 1/3 of the Earth.

Trees

Forests

Three types: tropical, temperate, and boreal (Taiga) --- depend on the latitude.

Warm, humid and found close to the equator.

Tropical Rainforests

Not much biodiversity. Any vegetation and wildlife living in a desert must have a special adaptation for surviving in a dry environment.

Biodiversity

Rainfall is less than 50 centimeters (20 inches) per year.

Dry

Deserts

Three types: hot and dry; semiarid, coastal, cold --- depend on the latitude.

Warm, humid and found close to the equator.

Hot Deserts

Activity

Presentation Next Meeting:

Choose a country within the Equatorial region and describe the following:

• Climate and weather

• Biome - vegetation and wildlife

• Hazards - What environmental hazards its inhabitants face?
