Sediment is transported through various mechanisms. Match the correct form of transportation to its mechanism.

This mechanism
causes rivers
to meander,
or curve.

Tides and
currents from
this mechanism
will transfer
sediments to
beaches across
the world.

This mechanism
causes mass
wasting and
landslides.

These slow-
moving, frozen
bodies transfer
large boulders
and sediment
to areas quite
far from their
original locations.

Lack of vegetation
means that this
mechanism will
become the
dominant force
for erosion and
deposition.
