Why do deltas oo-oop?

Answer 1

Deltas ooze or "oo-oop" as a result of sediment deposition at the river's mouth, where the river meets a body of water like an ocean or lake. This process occurs because the river’s velocity decreases, causing it to lose the sediment it carries. Over time, the accumulated sediment creates a delta, which can form various landforms such as islands and wetlands. The shape and characteristics of a delta are influenced by factors like water flow, sediment type, and tidal patterns.
