  • Slide 4 - What do we know about sandy beaches? Contains loose, unstable sediment. This sediment is easily moved around by wind and water. Beaches that face open ocean are characterized by large surf (breaking waves). The surf zone is constantly moving up and down with the tide. The surf zone is comprised of beach grasses, shrubs, trees (supratidal). Crabs and small fish live in the surf zone.

  • Slide 6 - What do we know about rocky beaches? Rocky beaches provide a more stable environment. Rocky beaches contain coves, crevices, and tunnels in which marine organisms can hide. Rocky beaches are divided into 3 tidal zones, depending on how high or low the tides are. Some organisms found in a rocky coastal beach environment are: barnacles, snails, sea urchins, starfish, algae, very small fish.
