Key Differences
A rock is a solid mineral formation found naturally on Earth, commonly used in various contexts ranging from construction to landscaping. On the other hand, a crag refers more specifically to a steep, rugged rock face, often seen as part of a cliff or mountain.
While rocks can vary greatly in size, from small pebbles to huge boulders, crags are typically large and imposing, frequently used as terms in climbing and hiking.
Rocks serve various functions, including building materials or decorative elements in landscaping. In contrast, crags are primarily known for their aesthetic and recreational values, especially in natural and scenic settings.
The study of rocks is a fundamental aspect of geology, helping scientists understand Earth's history and structure. Whereas, crags, while also studied by geologists, often hold more interest for ecologists and environmentalists studying specific habitats and ecosystems.
Rocks can be found worldwide in a multitude of environments, from riverbeds to deserts. Crags, however, are typically associated with more dramatic landscapes like mountain ranges and coastal cliffs.
