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).

Jun 19, 2024 · Dry lava is called igneous rock. When lava cools and solidifies, it transforms into solid rock. The resulting igneous rocks can have different compositions and textures, depending on the specific conditions of cooling. Some common examples of dry lava or igneous rocks include basalt, andesite, and rhyolite. What is a rough lava called?

Apr 2, 2025 · lava, magma (molten rock) emerging as a liquid onto Earth’s surface. The term lava is also used for the solidified rock formed by the cooling of a molten lava flow. The temperatures of molten lava range from about 700 to 1,200 °C (1,300 to 2,200 °F).

Aug 4, 2015 · Dry lava is called igneous rock. The superheated molten rock that reaches the surface in an eruption is called lava, and lava may flow for miles before cooling.

Apr 15, 2022 · What is dried lava called? Dry lava is called igneous rock. The superheated molten rock that reaches the surface in an eruption is called lava, and lava may flow for miles before cooling.

Oct 4, 2022 · Dry lava is called igneous rock. The superheated molten rock that reaches the surface in an eruption is called lava, and lava may flow for miles before cooling.

Aug 25, 2014 · There are two main groups: rocks that form from the solidification of lava flows (extrusive), and rocks that form from the compaction of solid volcanic fragments (pyroclastic).

Feb 28, 2019 · This ‘a‘ā flow erupted from fissure 8 on Kīlauea Volcano's lower East Rift Zone on June 1, 2018, shows how the interior of a lava flow remains incandescently hot even though surface cooling forms a crust of solid rubble.

Although lava may appear wet, it is actually hot and dry. This is because the intense heat of the molten rock evaporates any moisture that it comes into contact with. Lava can also cause nearby water sources to boil and evaporate, further contributing to its dryness.

Jun 25, 2013 · When lava meets ice, the resulting mess can cause flooding, destroy valuable resources and even produce explosions.
