← GeographyWhich volcanic outcome characterizes mid-ocean ridge divergent boundaries?
A)Fissure eruptions create basalt plains✓
B)Explosive eruptions deposit thick ash
C)Composite volcanoes form stratovolcano cones
D)Caldera collapses produce massive lahars
💡 Explanation
Fissure eruptions occur because decompression melting under the diverging plates allows magma to rise in extensive fractures creating new basaltic crust, rather than building steep cones, therefore creating basalt plains is correct rather than explosive activity.
