Lava Comes Only From Volcanoes Or at Donna Caron blog

Lava Comes Only From Volcanoes Or. Once magma reaches the surface through a volcanic vent or fissure, it becomes lava. Volcanoes can absolutely run out of magma. Volcanoes, of course, are the places where lava comes to the surface. The most obvious landforms created by lava are volcanoes. Once a volcano runs out of magma, it is considered extinct. In fact, most volcanoes are thought to only have enough magma for a few eruptions. Both magma and lava are hot! Magma’s temperature ranges from 600°c to 1,300°c (1,112°f to 2,372°f), depending on its composition and depth. Magma is not necessarily hotter than lava. Magmas vary in their chemical composition, which gives them—and the volcanoes that contain them. The term lava is also used for the solidified rock formed by the cooling of a molten. If this molten rock makes it to the surface and keeps flowing like a liquid, it's called lava. The hotter the magma, the more fluid it is. But, how hot they are varies. Just to keep things straight, geologists use the word magma for molten rock that is still underground, and the word lava once it has.
