Lava hardens, and the lava is turned into obsidian, or ignoeus rock.
Igneous rock is formed from solidified and cooled magma or lava.
Igneous rocks are formed when lava cools. After a eruption, the lava cools, and the igneous rock is formed.
The igneous rock forms from lava because when a volcano erupts the lava that flows from a volcano. Igneous rocks have a hot liquid in the beginning. The lava that flows forms into an igneous rock fast. When the lava reaches the surface, it cools rapidly and turns into igneous rock.
Intrusive igneous rocks are thusly formed.
The common usage of "lava rock" in the USA refers to a black rock with a number of visible bubbles or air pockets that is formed from cooled lava on the surface. Although lava rock is an igneous rock, it is not the same as the definition for the word igneous, which can also include igneous rocks which have solidified from magma below the surface.
lava becomes igneous rock by cooling down and hardening -ctd
Cooling lava produces extrusive igneous rock, such as basalt.
Extrusive igneous rock.
Solidified magma or lava is igneous rock.
the type of rock formed when lava or magma cools is igneous rock..
Yes, an igneous rock forms when lava is cooled. It is called an extrusive igneous rock (because lava is extruded onto the surface of the earth). A magma pool that did not erupt as lava can cool to become an intrusive rock.
lava cooling to become rock is a change of state from liquid to solid
