Ice volcano (original) (raw)
En isvulkan är ett meteorologiskt fenomen som bildas vid vissa meteorologiska förutsättningar. Vid mycket låga temperaturer bildas det en hållbar stark is. I kombination med starka vindar bildas det sprickor och hål i isen, i dessa hål sprutar sen vatten upp som fryser till is och bygger upp formen av en vulkan.

| dbo:abstract | An ice volcano is a conical mound of ice formed over a terrestrial lake via the eruption of water and slush through an ice shelf. The process is wave-driven, with wind providing the energy for the waves to cut through the ice and create formations that loosely mimic the shape and activity of volcanoes. After being ejected into the atmosphere, the liquid water and slush freeze and fall back to the surface, growing the formation. Ice may also be erupted. The phenomenon is most often observed along the southern coast of Lake Erie and Lake Ontario, when the temperature is below freezing and the wind blows onshore with a velocity of at least 25 mph (40 km/h). They are known to reduce coastal erosion there. The formations are temporary: they are frequently destroyed by storms and warm weather, and once the lake wholly freezes over, eruptions are no longer possible. There is no consensus name for this phenomenon. Due to its visual similarity to volcanism and particularly cryovolcanism, the term "ice volcano" is frequently used, but it remains controversial. Unlike geysers and related structures, ice volcanoes are not hydrothermal. The uplifts may attract a number of visitors, but they are dangerous, and experts warn that people may fall through the ice or slip into the cold lake. Ice volcanoes are used by snowy owls as hunting platforms to search for waterfowl. (en) En isvulkan är ett meteorologiskt fenomen som bildas vid vissa meteorologiska förutsättningar.
