"礁石" refers to reef rocks or rocky outcrops in the sea or rivers. These are often hazards for ships but also important habitats for marine life.
Common Contexts
You will often hear "礁石" in maritime navigation, marine biology, and coastal descriptions. It is a concrete noun describing physical features in water.
Collocations and Patterns
