Most likely a fast moving stream.
Bed Load
A stream can bounce large pebbles and boulders, along the stream bed. These rocks are called bed load. A stream can carry sand in suspension. These materials, called suspended load, make the river look muddy. The dissolved load is material carried in a solution, which means that the material is dissolved in the water. Sodium and calcium are some of the materials in the dissolved load.
It is believed that Jupiter has a rocky core, but it is unliekly that there are discrete rocks there.
One of the most popular ways of separating gold from rock, is gold panning, and it is a very big tourist attraction in Kalgoorlie WA (Australia).Gold panning usually takes place on the inside bend of a stream, and a wide and shallow pan is used. The pan is filled with rocks and gravel that might have gold concealed within them. The gravel, rocks (and possibly gold) is submerged in water, letting the much denser gold sink underneath the rocks, making it easy to collect.
The chemical composition of gravel would vary depending upon the geological make up of the rocks, shells etc that the gravel consists of.
Bed Load
The dissolved load is the chemicals absorbed by the water. Other load examples are gravel, sand and silt, carried downstream undissolved.
Rubbing against rocks along the stream channel
The none adhesive ova are released amongst the rocks and gravel of the creek/stream bed.
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
Depends on the size of the load. You'll have to be specific and tell exactly how much gravel there is.
Rocks
load or stream load.
I'm not sure why you would change the rocks (and I assume you mean gravel?) but you should vaccuum the gravel (with a special gravel washer) once a week.
