Exfoliation is a physical weathering process where rock layers peel away in sheets or slabs, often due to the release of pressure as overlying materials are removed. This process is common in large, homogeneous rock masses like granite, forming characteristic dome-shaped landforms. Exfoliation is significant in geomorphology and the study of weathering processes.
