  • Q:

    Why are there volcanoes?

    A:

    Volcanic vents allow the Earth to release built up gases from the heat and pressure emanating from its core. Magma rises towards the surface, and as the pressure builds the magma seeks outlets through which to flow. The higher the pressure build-up, the greater the volcanic explosion.

  • Q:

    What impact do volcanoes have?

    A:

    The primary impact volcanoes have on the environment is the release of volcanic gases into the atmosphere. Volcanoes release around 130 million tons of carbon dioxide each year, as well as toxic pollutants like sulfur dioxide, hydrogen sulfide, hydrogen chloride and hydrogen fluoride. However, volcanoes can also have a positive impact on the environment because the lava and ash produced by an eruption contain valuable nutrients for the soil.

  • Q:

    How are volcanoes measured?

    A:

    Volcanoes are measured and reviewed through the Volcano Explosivity Index, or VEI, which determines the quality of the volcano, the volume of the lava, how high the volcano measured at the time of eruption and how often the volcano explodes, according to the Old Farmer's Almanac. By reviewing each volcano against this criteria, it is simpler to determine which ones have had the most impact.
