← Earth & Natural SystemsIf a volcano erupts effusively, releasing basaltic lava onto a gentle slope, which consequence follows?
A)Formation of a steep stratovolcano
B)Violent pyroclastic density current
C)Rapid caldera collapse event
D)Development of a broad shield volcano✓
💡 Explanation
Basaltic lava has low viscosity and flows easily; therefore, effusive eruptions on gentle slopes allow lava to spread widely, building a shield volcano because the lava flows horizontally rather than piling up steeply as in stratovolcano formation.
