The action that describes chemical weathering is **water carving out a limestone cave**. This process involves the chemical reaction between water (often slightly acidic due to dissolved carbon dioxide) and minerals in the limestone, leading to the dissolution of the rock and the formation of caves.
The other options you mentioned are examples of physical weathering or erosion, not chemical weathering.
