Final answer:
Sand moves by saltation near the stream bottom, gravel and stones move by traction, while clay and silt move by suspension in the air.
Explanation:
Saltation is a process where somewhat bigger particles like sand are moved by jumping or bouncing near the ground, nudged along by water and other particles. Gravel and stones, on the other hand, move by traction, rolling or dragging along the bottom of the water. Clay and silt, being tiny particles, move by suspension, hanging in the air for periods, carried high above the ground at times.
