Learn what an oasis is and why it looks like a green island in the middle of sandy deserts. Perfect explanation for curious 8-year-old kids.
An oasis is like a special green island in the middle of a big, hot desert. Imagine a huge area covered with sand, where there are hardly any plants or water. In some places, underground water is really close to the surface. When this happens, water comes out and makes the land wet. Because of this water, plants like palm trees and grass can grow there.
This green spot with water, plants, and sometimes even animals is called an oasis. It is important for people and animals because it provides a place to rest, drink water, and find food in a desert where everything else is dry and sandy.
So, an oasis is a wonderful and life-giving place that looks like a green island surrounded by a big sea of sand!
