Explanation:

Volcanic Fumaroles  -

Fumaroles are basically a vent o the Earth's surface from which the steam and volcanic gases can escape out into the atmosphere . The groundwater is the major source of the Fumaroles to emit the water vapors .The gases like the sulfur dioxide , carbon dioxide and hydrogen sulfide are emitted directly from the magma . Fumaroles are present often on the active volcanoes .
