Which of the following regions is typical of the tropical climate zone?

The jungles of South America are representative of the tropical climate zone due to their warm temperatures and high levels of precipitation throughout the year. This climate zone is characterized by a consistent temperature range, usually between 20°C to 30°C (68°F to 86°F), with minimal seasonal variation. The substantial rainfall, often exceeding 2000 mm annually, supports lush, diverse vegetation typical of rainforests, which are abundant in regions like the Amazon Basin.

In contrast, North America has a variety of climates, including temperate and arctic regions, but does not fall under the tropical classification. The Arctic tundra is known for its cold temperatures and limited vegetation, while the Sahara Desert is characterized by extreme aridity, making it unsuitable for the lush growth found in tropical climates. Thus, the jungles of South America are distinctly aligned with the defining characteristics of the tropical climate zone.
