Which outcome results when excessive erosion reduces sediment reaching coastal streams?

💡 Explanation

Reduced sediment supply weakens sediment cell equilibrium along coasts because littoral drift depends on sediment input. Therefore the coastline becomes more vulnerable to erosion, rather than experiencing increased heat flux or changes to tectonic activity or up welling currents.
