UPSC Prelims 2024 – Products of Volcanic Eruptions

✅ Correct Answer: (d) All four

Explanation:

A volcano is an opening in the Earth’s crust through which molten material, gases, and solid fragments are expelled. The materials released during volcanic eruptions include:

• Pyroclastic debris such as volcanic bombs and fragments
