A wave in the oceans, is a ridge or swell
formed by wind or other causes. The power of
a wave is determined by the strength of the
wind and the distance of open water over
which the wind blows (the fetch). Waves are
the main agents of coastal erosion and
deposition: sweeping away or building up
beaches, creating spits and berms, and
wearing down cliffs by their hydraulic action
and by the corrasion of the sand and shingle
that they carry. A tsunami (misleadingly
called a `tidal wave') is formed after a
submarine earthquake.
