← GeographyWhich crustal deformation arises when a descending plate encounters increased mantle resistance?
A)Accretionary wedge formation✓
B)Oceanic fracture zone creation
C)Submarine canyon development
D)Abyssal plain subsidence
💡 Explanation
Accretionary wedge formation occurs because sediment accumulates on the overriding plate through offscraping during subduction; this deformation increases significantly when the descending plate encounters greater resistance. Therefore, an accretionary wedge forms, rather than features associated with faulting or erosion.
