Fumaroles
Fumaroles are openings in the Earth's surface that emit steam and gases, often found near volcanic activity. They are typically characterized by their strong sulfur smell and can reach temperatures of several hundred degrees Celsius. As a part of the "Volcanic Geysers" category, fumaroles share some similarities with geysers in that they both occur near volcanic areas and involve the release of gases and steam. However, while geysers erupt periodically and shoot out jets of water and steam, fumaroles constantly release gas and steam at a lower pressure. Fumaroles are a fascinating feature of volcanic landscapes and can provide valuable insights into the geological processes occurring beneath the Earth's surface. They add to the natural beauty and wonder of the places they are found in, making them an essential part of the "Natural Wonders" category.
