Question

Use the image to answer the question.

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.

Over time, the delta could undergo changes due to natural processes such as erosion, sediment deposition, and the movement of water. The river, as it continues to flow into the body of water, could carry and deposit more sediments, potentially causing the delta to expand and grow larger. This sediment deposition would contribute to the formation of new land areas within the delta. Conversely, if the river's water flow slows down or decreases, the sediment deposition may be reduced, and the delta could experience erosion, leading to a decrease in its size. Additionally, external factors such as climate change or human activities like damming or diversion of the river's water could also impact the delta's evolution over time.
