The coast line is the area where land meets the sea or ocean.

• It can be also defined  as the line which forms the boundary between the land and the ocean or sea.
• In the simplest words it is the land along a sea.
• Coast line measures around 620,000 kilometres  on Earth.
• It is Waves, tides, and currents which help in the formation of coastlines .
• Coastlines are formed when waves crash onto shore, and erode the land.
• Coastlines are important as it provide unique homes for marine plants and animals etc.
• Coasts also help us in understanding natural events, such as weather and changing sea levels.
