Understanding Natural Landform Processes: The Baseline

To understand thee magnitude of human influence, one mutt first understand thee fundamentamental processes that naturally shape thee Earth 's surface. These processes operate on timescoles ranging from seconds (a landslide) to millions of years (mountain building). The primary accordiies included erosion, weathering, transportation, deposition, and tectonic activity. Each interacts in complex feed back loops.

Erosion: Thee Wear and Transport of Earth Materials
