Which outcome occurs downstream of a glacial dam when rapid drainage begins?

💡 Explanation

A jökulhlaup causes alluvial fan deposition because meltwater releases with high energy, initiating substantial sediment transport; therefore, fans expand, rather than reefs building, which result from different triggers, like sea variations.
