Which of the following volcanic landforms is characterized by a broad, gently sloping cone built up by successive flows of low-viscosity basaltic lava?

💡 Solution & Explanation

Shield volcanoes are formed by successive eruptions of low-viscosity basaltic lava that travels great distances before solidifying, creating broad structures with gentle slopes resembling a warrior shield. Mauna Loa in Hawaii is a classic example of this volcanic type, contrasting sharply with steep-sided composite cones. Low silica content prevents explosive eruptions, allowing fluid lava flows to construct expansive dome-like mountain profiles over long geological periods.
