← GeographyAfter magma ascends following substantial eruptions, which volcanic structure readily develops due to effusive activity?
A)Volcanic dome formation✓
B)Deep oceanic trench
C)Rapid glacial calving
D)Coastal spit deposition
💡 Explanation
Volcanic dome formation readily develops due to lava with high viscosity extruding onto the surface because the effusive activity follows eruptions pushing magma out; therefore a dome results from the cooling lava rather than alternative geological features.
