Over time, the delta of the Yukon River in Alaska could undergo several changes.
1. Erosion and sediment deposition: The continuous flow of the river brings along sediment and debris which gets deposited at the mouth of the river. Over time, this sediment buildup can change the shape and size of the delta.
2. Formation of new distributaries: As the river enters the body of water, it branches out into several smaller streams of water. These smaller streams, known as distributaries, can change their courses over time due to changes in water flow, erosion, or other factors. This can result in the formation of new distributaries or the abandonment of existing ones.
3. Delta growth or shrinkage: The deposition of sediment can cause the delta to grow in size as new land is created. However, factors such as changing water flow, tides, and storms can also cause erosion and result in the shrinking or loss of delta land.
4. Vegetation growth and succession: Over time, vegetation such as trees, shrubs, and grasses may establish and grow on the delta, especially on the land portions. This vegetation can help stabilize the delta land and contribute to its growth. However, changes in water flow, storms, or human activities can also result in vegetation loss and impact the delta's stability.
Overall, the changes in the Yukon River delta over time would be influenced by various natural and human-induced factors like erosion, sediment deposition, changes in water flow, tides, storms, and vegetation growth.
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 of the Yukon River in Alaska could change through erosion and sediment deposition, the formation of new distributaries, delta growth or shrinkage, and vegetation growth and succession. Various factors like water flow, tides, storms, and human activities can influence these changes.
