Other times volcanoes can slowly leak hot lava from vents. Regardless of how volcanoes release this hot molten material, it is a sign of new birth in the rock cycle. This liquid-like rock, called magma, is released. Once it is above ground, it is called lava, and eventually, it cools to become fire rock, or igneous rock.
An igneous rock formed when magma is extruded onto Earth's surface where it cools and crystallizes, or when pyroclastic materials become consolidated. Plutonic (intrusive igneous) Rock Igneous rock that formed from magma intruded into or formed in place within the crust
Vesicles are air bubbles that form in extrusive igneous rock. What sub-type of igneous rock contains vesicles and why does it contain them? Vesicles are commonly found in extrusive igneous rock because of gases that form from lava as the material solidifies -- like bubbles in a bottle of soda when you open it.
