An oasis is a fertile area in a desert where water is available, allowing plants and animals to thrive. These unique spots often form around natural springs or underground rivers that surface, creating a lush environment amidst the arid landscape. Oases are crucial for travelers and wildlife, providing essential resources like water and food. Oases can support various vegetation, including palm trees and grasses, which attract animals and humans alike. They have historically served as important trade stops along routes such as the Silk Road, enabling commerce and cultural exchange in otherwise inhospitable regions.
