  2. Volcano - Wikipedia

    en.wikipedia.org/wiki/Volcano

    Most cinder cones erupt only once and some may be found in monogenetic volcanic fields that may include other features that form when magma comes into contact with water such as maar explosion craters and tuff rings. [27] Cinder cones may form as flank vents on larger volcanoes, or occur on their own.

  3. Volcanic impacts on the oceans - Wikipedia

    en.wikipedia.org/wiki/Volcanic_impacts_on_the_oceans

    The decreasing summer-time ice melting and precipitation due to the volcano cooling enhance the salinity near the Greenland Sea, and further reduces static stability, which means more surface water sinks into the deep ocean. The studies of Stenchikov et al. (2009) and Iwi (2012) suggest that both Krakatau and Pinatubo may have strengthened the ...

  4. Laze (geology) - Wikipedia

    en.wikipedia.org/wiki/Laze_(geology)

    Laze is acid rain and air pollution arising from steam explosions and large plume clouds containing extremely acidic condensate (mainly hydrochloric acid), which occur when molten lava flows enter cold oceans. [1] [2] The term laze is a portmanteau of lava and haze.

  5. Volcanology - Wikipedia

    en.wikipedia.org/wiki/Volcanology

    Volcanoes, he said, were formed where the rays of the sun pierced the earth. The volcanoes of southern Italy attracted naturalists ever since the Renaissance led to the rediscovery of Classical descriptions of them by wtiters like Lucretius and Strabo. Vesuvius, Stromboli and Vulcano provided an opportunity to study the nature of volcanic ...

  6. Volcanism - Wikipedia

    en.wikipedia.org/wiki/Volcanism

    Volcanism, vulcanism, volcanicity, or volcanic activity is the phenomenon where solids, liquids, gases, and their mixtures erupt to the surface of a solid-surface astronomical body such as a planet or a moon. [1]

  7. Volcanic gas - Wikipedia

    en.wikipedia.org/wiki/Volcanic_gas

    Water vapour is consistently the most abundant volcanic gas, normally comprising more than 60% of total emissions. Carbon dioxide typically accounts for 10 to 40% of emissions. [4] Volcanoes located at convergent plate boundaries emit more water vapor and chlorine than volcanoes at hot spots or divergent plate boundaries.

  8. Volcanogenic lake - Wikipedia

    en.wikipedia.org/wiki/Volcanogenic_lake

    A volcanogenic lake is a lake formed as a result of volcanic activity. [1] They are generally a body of water inside an inactive volcanic crater ( crater lakes ) but can also be large volumes of molten lava within an active volcanic crater ( lava lakes ) and waterbodies constrained by lava flows, pyroclastic flows or lahars in valley systems. [ 2 ]

  9. Lava delta - Wikipedia

    en.wikipedia.org/wiki/Lava_delta

    The Kilauea Volcano releases lava that flows down the slope of the volcano and eventually encounters the ocean; this lava flow hardens when it comes into contact with the significantly cooler water of the ocean and forms an unstable lava bench. Eventually, when the material beneath the lava bench stabilizes, it becomes stable land that has been ...
