What are four changes that a stream undergoes as it works its way toward the ocean?

As a stream flows toward the ocean, it undergoes several changes. First, it typically increases in volume and velocity as it gathers water from tributaries and runoff. Second, the stream channel often widens and deepens due to erosion, shaping the surrounding landscape. Third, sediment transport increases, leading to varying sediment deposition patterns and the formation of features like deltas at the mouth. Finally, the water quality often changes, with increased nutrient levels and temperature variations as the stream interacts with different environments.
