natural formation
Geology's own architecture
A natural formation is a geological or geographical feature created by natural processes rather than human activity.
Mountains, caves, canyons, and rock arches are natural formations, shaped over time by erosion, volcanic activity, or tectonic shifts.
The natural formation resembled a sleeping giant.
The phrase often appears in contexts distinguishing untouched landscape from artificial structures.
