The term for an area of land where no significant vegetation grows is called a desert. Deserts are characterized by extremely low rainfall, typically receiving less than 10 inches annually, which limits the types of plants and animals that can thrive there. Climate extremes often define deserts, with blistering hot days and chilly nights. Besides the classic sandy deserts like the Sahara, there are cold deserts, such as Antarctica, where harsh conditions result in minimal plant life. The ecology of deserts is fascinating, showcasing adaptations that allow surviving organisms to endure intense environmental stress.
