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.
(4 points)
Over time, the delta could change in several ways. Firstly, the river could continue to deposit sediment, causing the delta to expand further into the body of water. This would result in the creation of more land and potentially more branching streams.
Additionally, the shape of the delta could change due to erosion and deposition. Strong currents or storms in the body of water could erode parts of the delta, reshaping its formation. At the same time, sediment carried by the river could be deposited in new locations, causing the delta to shift or grow in certain areas.
Furthermore, vegetation such as trees and plants could grow on the delta, altering its appearance. As the vegetation takes root and grows, it could stabilize the sediments, preventing erosion and promoting the formation of new land.
Human activities could also impact the delta over time. For example, if the river is dammed upstream, the flow of water and sediment could be altered, affecting the growth and development of the delta. Additionally, if the land adjacent to the delta is developed or modified, it could impact the amount of sediment reaching the delta, potentially altering its shape and composition.
