Exploring Desert Biomes and Their Unique Adaptations

This video explores the desert biome, highlighting its global distribution, defining characteristics, and the adaptations of plants and animals to survive in extreme conditions. Deserts cover over one-fifth of Earth's land and are found on every continent. They are defined by receiving less than 10 inches of rain annually. The video discusses both hot and cold deserts, such as the Sahara and Gobi, and the unique adaptations of desert flora and fauna, like camels and cacti, to conserve water and withstand temperature extremes.
