Homonym: delta (Change)
A "delta" is a landform that occurs at the mouth of a river, where the river meets a larger body of water, like an ocean or a lake. As the river flows, it carries sediment, which is deposited when the water slows down. This creates a triangular or fan-shaped area of land, often rich in nutrients, making it ideal for agriculture and wildlife.
Deltas are important ecosystems that support diverse habitats. For example, the Mississippi River Delta in the United States is known for its unique wildlife and wetlands. Deltas also help protect coastlines from erosion and flooding, playing a crucial role in the environment.
