Intertidal Zone
The intertidal zone, also known as the littoral zone, is the area of the shore that is exposed to air at low tide and submerged at high tide. It is a unique and challenging environment that is constantly changing due to the rise and fall of the tides.
Characteristics of the Intertidal Zone
- Extreme variations in temperature, salinity, and water levels
- Abundance of sunlight and nutrients
- Presence of a diverse range of organisms adapted to survive in harsh conditions
- Erosion and deposition processes shaping the landscape
Organisms in the Intertidal Zone
Various organisms have adapted to the challenges of the intertidal zone:
- Marine algae: These photosynthetic organisms are essential for providing food and oxygen in the intertidal zone.
- Barnacles: These crustaceans attach themselves to rocks and other substrates, using their feathery legs to filter food from the water.
- Sea stars: These predatory echinoderms play a crucial role in maintaining the balance of the intertidal ecosystem.
- Hermit crabs: These crustaceans use empty shells for protection and are scavengers, feeding on detritus and dead organisms.
- Clams and mussels: These bivalve mollusks are filter feeders, consuming plankton and organic matter from the water.
Study Guide for the Intertidal Zone
To better understand the intertidal zone, consider the following questions:
- What physical factors contribute to the harsh conditions in the intertidal zone?
- How do organisms in the intertidal zone adapt to survive both underwater and exposed to air?
- What are the ecological roles of key intertidal organisms, such as algae, barnacles, and sea stars?
- How do human activities impact the intertidal zone, and what measures can be taken to protect this fragile ecosystem?
Exploring these questions will provide a deeper understanding of the intertidal zone and the fascinating adaptations of the organisms that inhabit this dynamic environment.

Earth/Space Science: Students will use scientific skills and processes to explain the chemical and physical interactions (i.e., natural forces and cycles, transfer of energy) of the environment, Earth, and the universe that occur over time.
Earth History: Explain how sedimentary rock is formed periodically, embedding plant and animal remains and leaving a record of the sequence in which the plants and animals appeared and disappeared.
Explain how sedimentary rock buried deep enough may be reformed by pressure and heat and these reformed rock layers may be forced up again to become land surface and even mountains.
Explain why some fossils found in the top layers of sedimentary rock are older then those found beneath in lower layers: Folding; Breaking; Uplift; Faulting; Tilting.
