This movement of sand and gravel particles is typically called littoral drift and is driven by waves, currents, and tides. It plays a crucial role in shaping Coastlines and beaches through erosion, deposition, and sediment transport. Human activities, such as coastal engineering structures or dredging, can also impact littoral drift processes.
Bed load is a term used in the field of geomorphology to describe the particles such as sand, gravel, and pebbles that are transported along the bed of a river or stream by rolling, sliding, or bouncing. These particles are too heavy to be suspended in the water column, unlike suspended load. Bed load movement can contribute to erosion and sediment transport in river systems.
Smelly
In water, sand will settle first due to its large particle size and weight, followed by gravel, pebbles, and soil in that order. The smaller and lighter particles take longer to settle as they are more easily suspended in the water.
The movement of large soil particles along the ground's surface after being loosened by saltation is known as traction. Traction occurs when the particles are too heavy to be lifted by the wind, so they roll or slide along the ground instead. This process can contribute to soil erosion and the transportation of sediment in windy environments.
Glaciers are able to carry large particles with ease due to their immense size and weight, which provides the necessary force to move and transport these particles. The ice in glaciers acts as a lubricant, reducing friction between the glacier and the ground, allowing it to slide and carry debris more easily. Additionally, the slow but continuous movement of glaciers over time helps to accumulate and transport large particles along their path.
Near shore, large sand and gravel particles are moved along the ocean bottom primarily by wave action and longshore currents. As waves approach the shore, they create currents that can transport sediments laterally along the coastline. Additionally, the back-and-forth motion of waves contributes to the movement of these particles, resulting in a process known as sediment transport. This dynamic movement plays a crucial role in shaping coastal landscapes.
Yes, water can pass easily through gravel because of the large pore spaces between the gravel particles. This allows water to flow through the gravel layer without much resistance.
the sand and gravel provide physical filtering of the water, and remove large particles. The Charcoal has very small pores, and a large surface area. it removes smaller particles and absorbs some chemicals and odors.

Yes, it is very important to rinse gravel before adding it to the tank to get rid of dust and debris. The tiny particles in the gravel can also just plain make a tank look bad until they have a chance to settle over a period of a few days. A large spaghetti strainer works well to rinse gravel and remove any of the smaller particles and debris.
Clay particles are very fine grained and light weight, so easily carried along by flowing water.

Large particles bounce and skip along the ground due to a combination of their momentum, the angle at which they impact the surface, and the properties of the material they are interacting with. When these particles hit the ground at an angle that allows them to deflect rather than absorb the impact, it causes them to bounce or skip.
Filtration effectively separates fine sand from coarse gravel by exploiting the difference in particle size. The filter's holes must be large enough to let the gravel pass through while retaining the finer sand. This process relies on the principle that smaller particles are trapped by the filter medium, while larger particles are allowed to flow through. Consequently, the result is a separation of the two materials based on size.
Decomposed granite is granite that is weathered and has been broken down into gravel sized particles. One can purchase a large supply of decomposed granite by ordering it from a home improvement store such as Home Depot or Lowe's.
