Which long-term consequence occurs in temperate grasslands when excessive topsoil erosion exposes nearby loess?

💡 Explanation

When topsoil erodes and reveals fine loess deposits, the newly exposed, unconsolidated sediment dramatically increases erosion rates which accelerates gully formation; this Landscape Incision mechanism causes stream channels to quickly deepen and incise because there’s now less resistance in the channel, therefore increased erosion, rather than slower soil development.
