True. When a river slows down, it loses its ability to carry large sediment particles, so it deposits them first. Smaller particles settle later as the energy of the river decreases further.
Yes, most sediment comes from weathering processes where rocks are broken down into smaller pieces by things like wind, water, and ice. These smaller rock fragments are then transported and deposited by natural forces like rivers, glaciers, and wind, eventually accumulating into sedimentary deposits.
Sediment forms through the weathering and erosion of rocks and minerals, which breaks down larger materials into smaller particles. These particles are then transported by natural forces such as water, wind, or ice, and eventually deposited in various environments like rivers, lakes, and oceans. Over time, layers of sediment accumulate and can become compacted and cemented, leading to the formation of sedimentary rock.
Yes, the average sediment size tends to decrease downstream due to the sorting process during transportation. As water flow velocity decreases, it can no longer carry larger particles, leading to their deposition closer to the source. Smaller particles are carried farther downstream before settling due to their lighter weight.
Silt has finer sediment compared to sand. Silt particles are smaller than sand particles, making silt feel smooth and silky to the touch.

No, the heavier are deposited first and then the medium ones and lastly the very smallest (sand). This can be seen clearly when you look at what are called out washed plains.

farther out into the body of water where the river empties
Graded deposits are a type of sorted deposit. Graded deposits have particles that are sorted by size, with larger particles settling out first followed by smaller particles. This results in layers of sediment that are sorted by particle size within the deposit.
Weathering and erosion processes break down the igneous rock into smaller particles, which are then transported and deposited as sediment by agents such as water, wind, or ice. Over time, compaction and cementation of these sediment particles can result in the formation of sedimentary rock.
It would take more time for smaller particles to settle because they are lighter than larger particles, making it harder for them to settle. Its is easier for larger particles to settle because if they bump up against each other they wont move much and their heavier weight will cause them to stay once settled.
The byproduct of the weathering of rocks is sediment. Weathering breaks down rocks into smaller particles that form sediment, which can then be transported and deposited in different locations by natural forces like water, wind, and ice.
During erosion, sediment particles are created as rocks are broken down into smaller pieces through processes like abrasion, weathering, and transportation. These sediment particles are then carried away by water, wind, or ice to be deposited elsewhere.
As distance from the shoreline increases in Dolphin Bay, the size of particles deposited tends to decrease while the density of particles deposited tends to increase. This is due to larger particles settling closer to the shoreline where wave action is stronger and can carry larger sediment, while smaller particles are able to travel further and settle in deeper waters.
