Deserturi, or deserts, are vast, dry regions characterized by minimal rainfall, extreme temperatures, and sparse vegetation. They cover about one-third of the Earth's land surface and can be found on every continent. Common types of deserts include hot deserts, like the Sahara, and cold deserts, such as the Gobi. Deserts are home to unique ecosystems and specially adapted plants and animals. Species like the cactus and camel have evolved to survive in harsh conditions. Despite their arid nature, deserts can be rich in minerals and resources, making them important for mining and energy production.
