Guiana Highlands

The Guiana Highlands is kind of like a giant hill or mountain range that is located in South America (the part of the world where Brazil, Venezuela, and Guyana are). You know how when you climb up a hill, it can get higher and higher? Well, the Guiana Highlands does that too, except it's really, really big and covers a lot of different places.

Now, there are lots of different things that make the Guiana Highlands special. One of the most important things is that it has a lot of different ecosystems. An ecosystem is like a big group of plants and animals that live in the same area and depend on each other for food and shelter. The Guiana Highlands has lots of different ecosystems because different parts of the mountain range are different heights, which means they have different climates and plants can grow in different ways.

Another thing that makes the Guiana Highlands special is that it has a really important river system. A river is like a big road for water, where it flows from one place to another. The river system in the Guiana Highlands is important because it provides water for people and animals that live near the mountains. It also helps plants and trees grow, which is important for the ecosystems we talked about earlier.

So, in summary, the Guiana Highlands is like a big mountain range in South America with lots of different ecosystems and an important river system.
