In geology, transportation refers to the movement of
eroded debris, whether by
rivers,
glaciers,
wind or
ocean currents and
tides. Particle sizes can vary from tiny
clay particles suspended in moving water, to
pebbles and
boulders. As the particles are transported, their edges can be smoothed, and is described as
rounding.
Deposition occurs when the speed of movement of the transporting medium becomes insufficient to hold the particles. Examples of such deposits are:
Bunter,
Moraine,
Overbank,
Dunes,
Tombolo.
