Which outcome necessarily accompanies increased effusive volcanic flow?

💡 Explanation

Shield volcanoes widen because effusive flow adds material that spreads thinly and widely outward via lava flows; therefore area grows, rather than becoming more prone to collapse, because a pressure buildup is not necessarily occurring.
