Fumaroles

Fumaroles are openings in the Earth's crust that allow steam and volcanic gases, such as sulfur dioxide and carbon dioxide, to escape from underground. They typically form in volcanic areas where the ground is heated by magma. When water seeps into the ground and gets heated, it turns into steam, which then rises to the surface and exits through these openings. Fumaroles can vary in size and activity, and their presence often indicates geothermal activity or potential volcanic eruptions, making them important for studying geology and volcanic behavior.
