उत्तर
The magma chamber of a volcano is a large underground reservoir where molten rock (magma) is stored beneath the Earth’s surface. It supplies magma to the volcano during an eruption. The magma in this chamber contains dissolved gases and crystals, and when pressure builds up, it forces the magma upward through vents, leading to an eruption.
