Estuary

Real World Example

Imagine trying to mix two different types of paint colors to create a new shade. Just like blending paints, an estuary is where fresh river water meets and mixes with salty ocean water, creating a unique environment. The river water is like one paint color, and the ocean water is like another; when they combine in the estuary, they interact to form a distinct mix, much like how new shades are created from different paints.
