Answer: True
Explanation: Streams create both erosion and deposition. This is true because as water flows in a stream, it has the power to erode the land and carry away sediment. This erosion occurs when the force of the moving water wears away the rock and soil along the stream banks and bed. The eroded material is then transported by the stream and can be deposited elsewhere when the water slows down or when the stream reaches a body of water like a lake or ocean. This process of deposition occurs when the stream drops the sediment it is carrying, which can contribute to the formation of new landforms or the buildup of sediment in certain areas.
