Moving water shapes land.
Water drains from land in drainage basins, which are
separated by divides. As water flows over land and
underground, it moves sediment and changes land
features.

Waves and wind shape land.
The action of water moves sand and builds up new
landforms, such as sandbars and barrier islands.
VOCABULARY
longshore drift
longshore current

Incoming waves push sand
up the beach at an angle.
longshore current

Waves and wind shape land.
The action of water moves sand and builds up new
landforms, such as sandbars and barrier islands.
VOCABULARY
longshore drift
longshore current
sandbar
barrier island
dune
loess
Waves and currents move and
build up sand deposits to form
a sandbar under the water
surface.
As more sand is deposited, the
sandbar rises above the surface
to become a barrier island.
