Which outcome arises when arctic soil experiences summer thaw?

💡 Explanation

Summer thaw saturates the active layer causing solifluction, a downslope movement of soil material due to gravity on the saturated soil, because reduced friction and increased weight facilitate motion; therefore mass displacement, rather than any alternative, occurs.

• Which landscape outcome results when permafrost prevents drainage, causing soil saturation?
• Which impact accelerates glacial melting when glaciers are covered by a layer of dark tephra?
• Which risk increases in a rapidly emptying magma chamber?
• Which phenomenon inhibits speleothem formation within submerged caves?
• Which outcome of glacial rebound causes crustal earthquakes?
• Which outcome arises when excessive development restricts floodplains near levees?
