Flowing water transports gravel, rocks, and boulders downstream by
rolling or sliding
them along the bottom of the streambed.
Small grains of sand and gravel can
bounce along the bottom
in a series of jumps.
Smaller sand, silt, and clay particles are transported in suspension. The particles move downstream
suspended in the turbulent water
, giving the water a muddy appearance.
Dissolved rock materials (not visible) move downstream in
