geological formations
Natural rock features
Geological formations are distinct bodies of rock or sediment with consistent characteristics—a particular type, age, or origin—that distinguish them from surrounding material.
The term covers natural structures shaped by erosion, deposition, or tectonic activity: The park is famous for its unusual geological formations.
Arches, caves, canyons, and volcanic columns are all geological formations.
Geologists use the term more technically for mappable rock units: The Morrison Formation contains many dinosaur fossils.
