Which crustal deformation results at a subduction zone?

💡 Explanation

Linear volcanic arcs form due to flux melting; the subducting plate introduces volatiles that lower the mantle's melting point, therefore magma rises and erupts through the overlying crust rather than forming ridges, valleys, or thinning crust.

• Which process dominates at higher elevations, accelerating weathering?
• Which outcome occurs when wind velocity decreases suddenly across desert dunes?
• Which outcome results from plate subduction along continental margins?
• Which geologic outcome intensifies when an oceanic plate subducts at a steeper angle beneath a continental plate?
• Which process most directly redistributes heat following intense insolation at the equator?
• Why may a growing lava dome collapse suddenly?
