Reasons for Iceland to be volcanically active

  • Geological Location
    • Mid-Atlantic Ridge: Iceland is situated on the Mid-Atlantic Ridge, where the Eurasian and North American plates are moving apart gradually.
    • Effect: This movement creates volcanic rift zones, where the Earth’s crust fractures, allowing magma to rise and sometimes erupt as lava and ash.
  • Hotspot Presence
    • Hot Zone: Iceland is also positioned over a hotspot, contributing to increased volcanic activity.
    • Effect: This hotspot leads to enhanced volcanic activity in the region, adding to the geological dynamics of the island.
