What are key features of a beach profile?

The correct answer identifies key features of a beach profile, which is crucial for understanding coastal geology and geomorphology. A beach profile is characterized by specific zones that contribute to its overall structure and dynamics. The foreshore refers to the area that is exposed at low tide and submerged at high tide, playing a critical role in wave interaction and sediment deposition. The backshore is the section of the beach that extends from the high tide mark inland, typically remaining dry and vulnerable to erosion from wind and storm action during extreme weather events. The berm is a ridge of sediment, usually sand, formed by wave action just above high tide, which serves to protect the backshore area during calm sea conditions.

These features collectively demonstrate how beaches are shaped by natural processes, providing insights into how they evolve and respond to environmental changes. Understanding these elements is essential for effective coastal management and conservation strategies. The other options may refer to coastal features but do not accurately encapsulate the organized structure and components of a beach profile as clearly as the identified features do.
