1. What is a geyser?A geyser is a natural fountain that shoots hot water and steam into the air. It happens when underground water gets very hot and builds up pressure until it bursts out. The water is usually heated by magma below the Earth’s surface.
2. How does a geyser erupt?When the hot underground water gets hotter than its boiling point, it turns into steam very quickly. The steam pushes the water up through a narrow pipe, making a big splash. After the burst, the system cools and refills with fresh water to start again.

Hydrothermal: Relating to or denoting geological activity involving heated underground water.
Cryovolcanism: Volcanic activity on icy moons or planets, erupting volatile substances like water, ammonia, or methane.
Sublimation: The process where a solid changes directly into a gas without becoming a liquid first.
