  • How hot is the lava in a volcano?

  • Now we’re talking a lot more heat. Lava, the melted rock that shoots out of volcanoes, can flow at temperatures of thousands of degrees Fahrenheit. Lava that’s on the cooler side comes out of volcanoes at only pizza oven-like temperatures of 570 F, according to the United States Geological Survey (USGS).

  • What is the temperature of lava when it is first ejected?

  • The temperature of lava when it is first ejected from a volcanic vent can vary between 700 and 1,200 degrees C (1,300 to 2,200 F). As you probably know, lava is molten rock that comes out of a volcano during an eruption. Although the Earth鈥檚 mantle is solid, it鈥檚 so hot that puddles of molten rock can form between…

  • What are some facts about lava?

  • When a volcano erupts most people associate it with hot flowing rocks. To know more facts about lava, some information about volcanoes is also needed. Most of the Earth鈥檚 surface is solid. In some parts, however, the crust is thin.

  • What is the temperature of ultramafic lava?

  • Ultramafic lavas such as komatiite are rich in magnesium and have the highest temperatures. It is believed that such lavas erupted at temperatures of 1,600 C (2,910 F). At such temperatures, the lava viscosity is as low as water! However, there have been no modern ultramafic eruptions, with only a few occurring in the past 500 million years.
