TITLE
Kilauea is the world’s most active volcano. Hot liquid rock flows from its crater. From May to August 2018, 320,000 Olympic-size swimming pools’ worth of lava was released. It has been continuously erupting since 1983.
Magma is hot, hot, hot! Scientists estimate that molten rock below Kilauea Volcano in Hawai’i is about 2,700 degrees Fahrenheit (1,500°C). The magma cools as it moves toward the surface over time. Once the magma cools to about 1,830 degrees Fahrenheit (1,000°C) or less, it can’t flow like a liquid. It starts to turn into a solid. If it continues to cool, it will eventually form an igneous rock.
