← GeographyWhich volcanic phenomenon results following ice sheet removal?
A)Isostatic rebound induced magmatism✓
B)Pyroclastic flow driven subsidence
C)Lahar formation due to rainfall
D)Shield volcano lava dome collapse
💡 Explanation
Isostatic rebound decreases pressure on the mantle; decompression melting creates magma because reduced lithostatic pressure prevails; therefore, enhanced volcanism follows ice sheet removal rather than other volcanic hazards dependent on rainfall conditions.
