Stream Velocity VS. Sediment Size
A streams velocity is 100 cm/sec. List the
sediments that will be carried by the stream.
A streams velocity is 40 cm/sec. List the
sediments that will be carried by the stream.
State the relationship between stream velocity
and particle size.
Describe how the size and shape of most
pebbles change when the pebbles are
transported in a stream over a great distance.
