Are plains ever found along coastlines?

Yes, plains can be found along Coastlines, often referred to as coastal plains. These areas are typically characterized by flat or gently rolling terrain and are formed by the accumulation of sediment from rivers and ocean waves. Coastal plains can support diverse ecosystems and are often used for agriculture and urban development due to their fertile soils and relatively mild climates. Examples include the Atlantic Coastal Plain in the United States and the coastal plains of various countries around the world.
