← GeographyWhich outcome occurs when magma buoyancy exceeds lithospheric strength?
A)Surface volcanic eruption forms✓
B)Regional metamorphic rock creation
C)Increased seismic fault lubrication
D)Enhanced crustal plate subduction
💡 Explanation
When buoyant magma overcomes lithospheric strength, magma diapirism pushes the magma to the surface forming a volcano; because volcanic eruptions occur, rather than subduction that would require convergent plate boundaries or metamorphism from pressure.
