Which crustal outcome primarily occurs on continents overriding a subducting oceanic plate?

💡 Explanation

Volcanic mountain ranges form at subduction zones because slab-derived fluids trigger partial melting in the mantle wedge, resulting in magmatism forming composite volcanoes, therefore consistent mountain building rather than other tectonic structures.

• Which consequence results when excessive groundwater extraction lowers the water table beneath an alluvial aquifer?
• Which consequence results when intense wave action erodes the base of a coastal headland exhibiting differential weathering?
• Which outcome occurs when freeze-thaw cycles saturate the active layer in an area undergoing solifluction?
• Which feedback on coastal ecosystems results when large gyres stagnate?
• Which process critically contributes to the cyclical formation of kettle lakes within glacial landscapes?
