Since silicic magmas are colder and goopier than mafic magmas, dissolved gases have a harder time venting out of them. This ...

Volcanos are releasing ash and smoke into the atmosphere on three continents. That might be making you think back to your elementary school science class when you probably studied volcanoes and lava.

Magma becomes lava when it rises up to the Earth’s surface, like when the Nyiragongo volcano erupted in the Democratic Republic Congo in 2020. Igneous rocks are formed when magma and lava solidify.

HONOLULU — Hawaii’s Kilauea volcano resumed erupting Friday by shooting an arc of lava 100 feet into the air and across a section of its summit crater floor. It was Kilauea’s 31st display of molten ...

Magma is the molten material beneath the Earth's crust. It usually collects in a magma chamber beneath a volcano, and can then be injected into cracks in rocks or issue out of volcanoes in eruptions.
