Coastal Landforms Created by Wave Erosion: A E42
Sea stacks are offshore
columns of resistant rock
that were once connected
to the mainland. In these
instances, waves have
eroded the mainland,
leaving behind isolated
columns of rock.
Sea caves form when
waves cut large holes
into fractured or weak
rock along the base
of sea cliffs. Sea caves
are common in cliffs
composed of sedimentary rock.
Sea arches form
when wave action
continues to erode
a sea cave, cutting
completely through
the rock.
