Oasis is a place in a desert where water is available. This water can come from underground sources or surface springs. Because of the water, plants such as trees and crops can grow there. Oases often appear as green areas surrounded by dry land.

Oases are found in desert regions around the world, including parts of Africa and the Middle East. They exist where water reaches the surface or can be accessed from below. Oases support plant life, animals, and human settlements. People may use them for farming, travel stops, or living areas.
