The story behind the word. The word "erosion" comes from the Latin verb "erodere," which means "to gnaw away." Imagine a relentless animal slowly chewing at something until it's gone. This vivid image perfectly describes how natural forces like water, wind, and ice slowly but surely "gnaw away" at the Earth's surface, carrying bits of it away over time.
