Yes, because it erodes
Streams carry the largest part of their load near their source, where they have the most energy and ability to transport sediment. As streams move downstream and lose energy, they deposit sediment in the form of gravel, sand, silt, and clay.
Silt and clay.
The correct answer is silt and clay.
High gradient streams have steeper slopes, which means they have more energy and power to transport larger sediment particles. The fast flowing water in high gradient streams can effectively carry and move these large particles due to the force of the water flow.
Sediment
Wind, water, ice, and gravity are the main forces that carry sediment. Wind can transport fine particles over long distances, while water can move sediment through rivers, streams, and ocean currents. Ice can transport sediment when it freezes into glaciers, and gravity can cause landslides and rockfall to move sediment downhill.
Streams erode sediment primarily during times of high flow or flood events when the velocity and volume of water are increased. The force of the water helps carry and transport sediment downstream, causing erosion along the streambed and banks. Wind and ice can also contribute to sediment erosion in streams.

When their velocity decreases
sediment
Streams lose their ability to carry sediment primarily due to a decrease in water flow velocity, which can occur in low-gradient areas or during periods of low rainfall. When the flow slows down, sediment settles at the bottom, leading to sedimentation and the formation of bars or islands. Additionally, vegetation growth and human interventions, such as dam construction, can further reduce sediment transport by stabilizing the riverbed and altering the natural flow dynamics. Ultimately, these changes can impact the river's ecosystem and its ability to shape the landscape.
Odd question! All its features developed: the cave's passages and chambers, its speleothems, its sediment deposits. If any of the system's passages still carry streams, they are known as "active" and are still forming.
