Facts about Lava talk about the molten rock. During an eruption of a volcano, the molten rock will be expelled. It can be found not only on earth, but also in other planets. The geothermal energy located within the earth melts the rock due to the high temperature of heat. Lava is in the form of liquid when it is erupted from the volcano. It has the temperature of 1,292 to 2,192 degree F or 700 to 1,200 degrees Celcius. Check other interesting facts about lava below:
Facts about Lava 1: what is a lava flow?
During the non-explosive effusive eruption, the lava flow is created. This lava is in a moving outpouring state.
Facts about Lava 2: the solidification
The lava will be solidified into the igneous rock when the lava flow stops moving. Some people often used the word lava to call the shortened version of lava flow.

Facts about Lava 3: the distance
The distance covered by the lava flow is very large due to its shear thinning and thixotropic properties.
Facts about Lava 4: the explosive eruptions
Lava flows are not always expelled during the explosive eruption. The volcanic ash and tephra are expelled from the volcano.
Facts about Lava 5: the word lava
The word lava is derived from the Italian word. Some state that it is taken from Latin word of labes. The meaning of the word is slide or fall.
Facts about Lava 6: the first use of lava word

Facts about Lava 7: the components of lava
The silicate minerals are considered the most dominant materials found in lava. Quartz, micas, amphiboles, olivine, feldspars and pyroxenes are some silicate materials in the lava.
Facts about Lava 8: Igneous rocks
When the lava cools and solidifies, it will form the igneous rocks. There are three chemical types of igneous rocks. They include the mafic, intermediate and felsic ones.

Facts about Lava 9: the chemistry of lava
There are several factors, which affect the chemistry of lava such as the mode of eruption, viscosity and magma temperature.
