Desert

Deserts are environments with low rainfall, covering a third of Earth's surface. They can be hot or cold, with Antarctica being the largest cold desert and the Sahara the largest hot desert. Desertification is causing some areas to become deserts. Rain is rare but can be heavy, and irrigation is used to support life. Unique plants and animals have adapted to survive in these harsh conditions, with cacti storing water and animals like snakes and lizards thriving in hot deserts, while seals and penguins live in cold deserts near the ocean.
