Global climate zones

Divided into three zones: Hot (near equator, e.g., Australia), Temperate (mid latitudes, e.g., Serbia), and Cold (near poles, e.g., Canada).

Hot climates location and types

Found between 30 degrees north and south of the equator. Three types: Equatorial, Savannah, and Hot deserts.

Hot desert location

Between 15 and 30 degrees north and south of the equator.

Hot desert precipitation

Very dry, with less than 10mm of rain per year.

Hot desert temperatures

Ranges from 30 to 50 degrees, with very different temperature ranges between day and night.

Desert natural vegetation

Scarce due to severe water shortage; plants must adapt to hot, dry conditions.

Desert plant adaptations

Deep tap roots and widely spaced plants that find underground water, store water, and survive the heat.

Human activity in deserts

Limited due to climate; severe drought has caused people to migrate and settle in towns.

Desert tourism

Increasing due to areas of natural beauty.

Negative human impact in deserts

Can cause desertification.
