Question

question 1-5
which of the following is most likely caused by chemical weathering?
○ cirques carved out by a melting glacier
○ u - shaped valleys formed in a mountain region
○ rocks and sediment transported and deposited
○ unrecognizable facial features on a marble statue

Explanation:

Chemical weathering involves chemical reactions breaking down materials. Marble (calcium carbonate) reacts with acidic rainwater, causing gradual erosion of facial features. Cirques and U-shaped valleys are glacial (physical) processes; transported sediment is deposition. Only the marble statue's feature loss stems from chemical weathering.

Answer:

unrecognizable facial features on a marble statue
