← GeographyWhich consequence results when crustal divergence is restricted?
A)Increased magma chamber pressure results✓
B)Reduced seafloor spreading rate
C)Enhanced mantle convection upwelling
D)Fault zone metamorphic reaction decrease
💡 Explanation
A limited crustal divergence increases pressure from magma upwelling because magma cannot dissipate efficiently via volcanism; therefore magma chamber pressure rises rather than seafloor spreading slowing without divergence or mantle convection enhancement alone.
