Our planet is varied. There are deserts, rain forests, oceans, and mountains. In some places, the temperature rarely rises above 0°F. In other areas, it hardly ever dips below 100°F.
Some places are home to rhinoceroses, while others host elk or polar bears or kangaroo rats. Areas with similar climates, geography, animals, and vegetation are called biomes. Each biome on Earth has a unique combination of conditions that allows certain life forms to thrive there. Not all scientists agree on exactly how to divide Earth into biomes. Here’s one popular way.
