Final answer:
Bed load comprises larger sediment pieces like sand and gravel; Suspended load holds small silt and clay particles in water suspension; Dissolved load involves minerals as ions dissolved in water.
Explanation:
Bed load consists of larger pieces of sediment like sand, gravel, and boulders, not easily suspended in water but moved by the river through rolling and bouncing along the riverbed. Suspended load contains small particles of silt and clay that stay suspended in the water due to their size until the water nearly comes to a stop. Dissolved load includes minerals carried in water as dissolved ions, such as calcium from limestone bedrock, not dependent on flow velocity.
