Which outcome results when decreased sea ice alters Arctic streams?

💡 Explanation

Decreased sea ice causes increased coastal erosion because it exposes streams to greater wave action. Stream discharge reduces, contributing to lower freshwater cap thickness via basal melt, rather than increasing ocean circulation or stabilizing permafrost.
