Global Biogeographic Regions

Global biogeographic regions are areas of the world characterized by distinct climates, plants, and animals due to their geographic and environmental features. Scientists classify the Earth into different regions—like the Amazon rainforest, the Sahara Desert, and the Arctic tundra—based on shared ecological characteristics. These regions help us understand biodiversity and how species adapt to their surroundings. Factors such as temperature, rainfall, and the presence of mountains or oceans influence the types of life found in each area, shaping unique ecosystems across the globe.
