Question

question: whats formed if the magma chamber beneath a volcano empties during an explosive eruption, and the interior of the volcano can no longer support the weight of the mountain above it? answer options: select one of four cinder cones crater conduit caldera

Explanation:

To solve this, we analyze each option:

• Cinder cones: Formed by small fragments of lava (cinders) piling up, not related to magma chamber emptying.
• Crater: A bowl - shaped depression at the top of a volcano, usually from minor eruptions, not from the collapse due to an empty magma chamber.
• Conduit: The passage through which magma travels to the surface, not a feature formed by the collapse of the volcano.
• Caldera: Forms when a magma chamber empties during a large eruption, and the volcano's structure can't support the overlying mountain, leading to a collapse and a large, depression - like feature.

Answer:

D. Caldera
