turbulence
Sand is gradually carried down the beach by Longshore Drift.
Streams consist of moving water going down hill which has more kinetic energy and momentum than wind which is caused by the uneven heating of the planet (the heated air from one zone rises as the cooler air from another zone takes its place). It also might have to do with the fact that many particles can float in water but air is lighter than most things so the particles are heavier(not in the air, in the carried particles).
I would consider tiny pieces of rock carried by water to be sediment. Sediment is generally clay or sand particles, but any type of rock ground into fine particles can be carried by water. This may include igneous-type rocks (those that come from around volcanoes and the bottom of the ocean).

Sediment that is moved along the bottom of a stream is known as bed load. This consists of larger particles like gravel and pebbles that are transported by rolling, sliding, or saltation along the streambed.
The largest part of a stream's load is usually the bed load, which consists of larger particles like sand, gravel, and boulders that are transported along the stream bed through processes like rolling and sliding. These particles are too heavy to be suspended in the water column for long periods of time.
Particles of sand, gravel, or soil carried by the natural flow of a stream on or immediately above its bed. Also known as bottom load.Read more: bed-load
Because they are looking for food and may pick up gravel as they slurp their way along the bottom of the tank.
The sediment that moves along the bed of a stream is called bedload. Bedload consists of larger particles such as sand, gravel, and boulders that are transported by rolling, sliding, or bouncing along the streambed.
The difference between a suspended load and a bead load is a suspended load consists of the small particles or rock materials that are dispersed throughout the water and easily carried downstream. The bead load consists of the larger particles that are dragged and bounced along near the bottom of the river.
Sand is gradually carried down the beach by Longshore Drift.
The particles bouncing along a stream bottom is called saltation. This process involves particles being lifted and transported by the flow of water, before being dropped or settling back to the stream bottom. Saltation is common in streams with moderate flow velocities and bed roughness.
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.

Suspended load refers to sediment particles carried in the water column, while bed load refers to sediment particles that are transported along the riverbed through rolling, sliding, or saltating movements. Suspended load is typically finer particles that remain suspended in the water, while bed load is larger particles that move along the riverbed.
