  • Basaltic Lava Volcanoes: Formation & Types - Geology Science
    Volcanoes made of basaltic lava are typically shield volcanoes and fissure volcanoes. Here's why:

    * Basaltic Lava: Basaltic lava is very fluid, with low viscosity. This means it flows easily and spreads out over large areas.

    * Shield Volcanoes: Shield volcanoes have broad, gently sloping sides. They are formed by the accumulation of many layers of fluid basaltic lava.

    * Fissure Volcanoes: Fissure volcanoes erupt from long cracks in the Earth's crust. The lava flows out in vast sheets, creating extensive plains of basalt.

    Examples of volcanoes made of basaltic lava:

    * Mauna Loa (Hawaii): The largest active volcano on Earth, a shield volcano.

    * Kilauea (Hawaii): Another famous shield volcano known for its frequent eruptions.

    * Iceland: Iceland has numerous shield volcanoes and fissure volcanoes that erupt basaltic lava.

    It's important to note: Not all volcanoes erupt only basaltic lava. Some volcanoes can erupt a variety of lavas, including more viscous andesite and rhyolite.
