You're asking for something that's *not* erosion. Erosion is the process of wearing away and transporting soil, rock, or other material by natural forces like wind, water, or ice.

Here are some examples of things that are *not* erosion:

* Weathering: This is the breakdown of rocks, soil, and minerals through direct contact with the Earth's atmosphere. While weathering can *lead* to erosion, it's not erosion itself.

* Deposition: This is the process of dropping off sediment that has been transported by erosion. It's the opposite of erosion.

* Volcanic activity: While volcanoes can reshape the landscape, the process is more about creating new land than wearing it away.
