What best describes a tidal pool?

• A. A shallow pool of seawater that forms on the rocky intertidal zone, home to various marine organisms
• B. A deep-sea trench
• C. A freshwater lake
• D. A man-made pond

Answer: (A)

Tidal pools form when seawater gets trapped in depressions on the rocky shore as the tide goes out, creating shallow pools in the rocky intertidal zone. These small, saline habitats host a variety of marine life that can cope with changing water levels and salinity, such as algae, snails, crabs, sea stars, and anemones. This description matches a shallow pool of seawater on the rocky shore that serves as a home to diverse organisms. It isn’t a deep-sea trench, nor a freshwater lake, and it isn’t typically a man-made pond.
