The volcanic eruption is a geological phenomenon where magma rises to the Earth's surface. It occurs when molten rocks in the magma chamber rise to the volcanic pipes or diatremes. As it travels to the central vent, the gases expand and water turns into steam, creating intense pressure. When the pressure is too strong and cannot be contained, the volcano starts to erupt where magma turns into lava as it reaches the Earth's surface, volcanic ashes, and various gases release through the crater and secondary openings or parasitic vent.

Answer:
A volcanic eruption happens when magma erupts onto the Earth's surface.
Explanation:
This molten rock, along with gases and ash, escapes through a volcano. When magma reaches the surface, it's called lava.
Volcanic eruptions can be mild with slow lava flows, or they can be violent and explosive, affecting the environment and people nearby.
These eruptions are caused by the movement of tectonic plates and the buildup of pressure from molten rock and gases beneath the Earth's surface.
