Lava is molten or partially molten rock ( magma) that has been expelled from the interior of a terrestrial planet (such as Earth) or a moon onto its surface. Lava may be erupted at a volcano or through a fracture in the crust, on land or underwater, usually at temperatures from 800 to 1,200 °C (1,470 to 2,190 °F).

Lava is the most common form of material erupted from volcanoes that form oceanic islands like the Galápagos and Hawaiian Islands. Lava flows are usually only 1-10 meters thick, but some flows can be as thick as 50-100 meters, depending on the type of lava and the volume of the eruption.

Jun 21, 2019 · The glowing red-orange material is molten rock from deep below the Earth’s surface. When it erupts and flows on the surface, it is known as lava. When lava flows, it creates interesting and sometimes chaotic textures on its surface. These textures let us learn a bit about the lava.
Feb 27, 2023 · Lava lakes are among the planet’s most unusual geological features. Though there are about 1,500 active volcanoes on Earth, Mount Michael is only the eighth lava lake to be discovered.
Lava is hot, liquefied rock that flows from a volcano or other opening in the surface of Earth. When the liquid rock is still underground it is known as magma. Igneous rock is formed when lava cools and hardens.
Lava is magma, hot molten rock that flows through holes in the Earth's crust and onto the surface. Like magma, lava can be either viscous (~thick) or fluid (~thin). [1] Blocky lava is so thick and slow that it barely moves along the ground.
