A coastal plain is a flat, low-lying piece of land next to the ocean.Coastal plains can form in two basic ways.
i) Some start as a continental shelf, a flat piece of land located below sea level. When the ocean level falls, the land is exposed, creating a coastal plain. Sometimes, these coastal plains can extend far inland.
ii)A coastal plain can also develop when river currents carry rock, soil and other sedimentary material into the ocean. Layers of this deposited sediment build up over time, creating a gently sloping landscape.
For example- One coastal plain in Alaska features layers of sand and shells, alongside fossilized whale bones. Much of the sediment came from the nearby Appalachian mountains, and the plain required several thousand feet worth of material to form. Sometimes these areas give rise to fertile lands, like the Oxnard Plain in California, which is particularly suitable for growing strawberries.
Coastal plains are separated from the rest of the interior by nearby landforms, such as mountains.

Answer: In the coastal regions,the wind and the waves blow the sand and carry the material from the beach and deposit them further inland to form plains.
For example: Eastern and Western Coastal plains of India.
