Coastal landforms are natural features found along the edges of oceans and seas. They are shaped by the constant movement of water, wind, and waves. Common examples include beaches, cliffs, and estuaries. Each of these landforms plays a vital role in the ecosystem, providing habitats for various plants and animals. The formation of coastal landforms is influenced by factors like erosion and sediment deposition. For instance, waves can erode rocks to create caves and arches, while sand carried by water can build up to form dunes and barrier islands. Understanding these landforms helps us appreciate the beauty and complexity of coastal environments.
