Question

Quizplus · Accepted Answer

Continental rifts are characterized by large volumes of basaltic lava that are erupted from fissures. These eruptions are typically non-explosive and result in the formation of flood basalts, which are thick, extensive sheets of lava that can cover areas of thousands of square kilometers. Pyroclastic flows and ash-fall tuffs are typically associated with explosive volcanic eruptions and are less likely to occur at continental rifts.
