How did James hutton discover erosion?

James Hutton, often regarded as the father of modern geology, discovered erosion through his observations of natural landscapes in Scotland, particularly in the Siccar Point area. He noted the layers of rock formations and their relationship to the surrounding topography, recognizing that the processes of weathering and erosion shaped the Earth's surface over long periods. Hutton's work emphasized the slow, continuous nature of geological change, highlighting how erosion contributed to the formation of sedimentary layers. His insights laid the groundwork for understanding the Earth's dynamic processes over geological time.
