Best answer

Lava flows arestreams of molten rock that pour or ooze from an erupting vent. Lava is erupted during either nonexplosive activity or explosive lava fountains.

  • What is lava flow like?

  • In its original state, lava flows very much like a very thick fluid, a kind of honey. Lava flow creates different types of lava tubes. However, once the lava鈥檚 exposed to air, it could also cool into solid rocks. So the fact that lava can transition from the fluid into a solid makes its flow quite complicated.

  • How many types of lava flows are there?

  • There are two types of lava flows. 1. Mafic or basaltic lava flows: Basaltic or mafic lava means lower viscosity which means it is more likely to flow readily. Basalt melts at an extremely high temperature because it contains more of those mafic minerals like olivine and pyroxene with extremely high melting temperatures.

  • What is lava?

  • What is Lava? When a volcano erupts, the molten rock (or magma) that comes out of the Earth is called lava. Because lava is so hot (more than 1,100 degrees C, over 2,000 degrees F), it remains molten and flows across the ground until it cools and hardens into rock.

  • Why does tube-fed lava travel farther than open lava?

  • Consequently, tube-fed lava may remain at elevated temperature at a constant effusion rate for a longer time than in open flow, and thus can travel greater distances. Lava tubes are known to develop only in fluid flows of basaltic composition. They are common in p膩hoehoe flows, but can also form in a’膩 flows.
