Transcript Wave Cut Platform

Sea waves: It is formed due to friction of blowing wind
over it. High velocity wind produces high altitude waves
Cliff: It is steep rocky coast rising
vertically above the sea water. Cliffs are
formed by erosion of coastal rocks by
the action of breaking waves.
Wave Cut Platform: The flat area from
the cliff to the sea water is called wave
cut platform. Due to continuous erosion
of the rocky coast the cliff recedes
[move backwards] forming a flat area
called as wave cut platform.
Beach: Beach is formed by continuous
erosion of rocks and deposition of sand
by the breaker sea waves. Beaches are
very attractive for tourist.
Bars & Barriers: Sea waves when
parallel to the sea coast move, they
deposit sand parallel to the coast. It is
called as bars. Larger forms of bars are
called barriers.
Lagoon: It is a lake in the sea. It is
formed when a part of the sea water is
completely closed by bars or barriers.
Chilka Lake in Orrisa is the best
example.
lagoons are lakes and are very
important for fishing and internal
waterways. They are formed when bars
and barriers completely enclosed a
portion of sea.
Arch: Caves are formed in the coast
due to erosion by sea waves. When two
caves are joined due to further erosion
the whole structure is called as ‘arch’.
Stack: When roof of the arch is
collapsed due to further erosion the
standing pillar is called as ‘stack’ .
