What outcome is observed when excessive topsoil erosion exposes underlying loess deposits to increased surface runoff events from agricultural irrigation?

💡 Explanation

Excessive topsoil loss leads to increased nutrient transport via overland flow, triggering algal blooms and oxygen depletion, creating aquatic dead zones; this is because nutrient runoff is the dominant transport mechanism; therefore, eutrophication occurs rather than other soil-related phenomena like sinkholes.
