A satellite image of a river delta. On the bottom right side of the photograph is land with mountains and trees. A river comes from the bottom of the image and goes upwards. On the top right of the image is a body of water. As the river enters the body of water, it branches out into several smaller streams of water. At the locations where the river enters the body of water, there is a light-colored substance.
The image is a photograph of the Yukon River delta in Alaska. Describe how the delta could be changed over time. in 4 sentences and like a 8th grader
Over time, the Yukon River delta in Alaska can change in different ways. The river carries sediment, like dirt and rocks, from the mountains down to the delta. This sediment can build up at the mouth of the river, making the delta bigger and the land might extend into the water. The river also splits into smaller streams, and these could change course over time, creating new paths and patterns. The light-colored substance at the river entry points could be sand or silt deposited by the water, and this could change the shape and size of the delta too.
