Large, basin-shaped depressions that form when summit materials on a volcanic mountain collapse inward after an eruption or loss of magma are known as calderas. Option A, cinder cones, are small volcanic cones made up of tephra (volcanic fragments) that accumulate around a single vent. Option B, craters, are typically circular depressions located at the summit of a volcano or on its flanks caused by explosions or collapse of the volcano. Option D, domes, are volcanic features that develop from the extrusion of viscous lava that piles up around a vent to form a rounded or elliptical dome-shaped structure.
