Tide Pools: Tide pools are small depressions formed in rocky intertidal areas that hold seawater even at low tide. They create unique microhabitats supporting diverse organisms adapted to survive in harsh conditions.

Wave Action: Wave action refers to the movement and force of waves crashing onto the shore. It plays a significant role in shaping coastal landforms, eroding cliffs, and depositing sediments.

Zonation: Zonation is the distinct pattern of plant and animal communities found in different zones along a shoreline. It is influenced by factors such as wave exposure, salinity, and substrate type.
