Which outcome on land occurs when continental divergence stalls after lithospheric stretching?

A)Fissure volcanism across vast plains
B)Folding of strata near the rift
C)Formation of shield volcanoes underwater
D)Development of a transform fault

💡 Explanation

Fissure eruptions will occur because decompression melting of the asthenosphere causes magma to rise slowly through developing fractures, leading to distributed volcanism, therefore expansive basalt plains form, rather than folding, underwater volcanoes or transform faults during ongoing expansion.
