(地形学)
地貌学
the scientific study of landforms, their origin, development, and classification, often examining the processes that shape the Earth's surface, such as erosion, deposition, and tectonic activity
(钟乳石)
石笋
a tapering, icicle-like mineral formation hanging from the roof of a cave or underground structure, typically composed of calcium carbonate deposited by dripping water containing dissolved minerals
