Timescale sorts earth processes by how quickly they actually happen. Wikipedia notes that "human activities have increased by 10-40 times the rate at which soil erosion is occurring globally," showing the same natural process can run far faster once people speed it up. Browsing by timescale groups processes that unfold over a similar span of time.
