Volcanic (Extrusive) igneous rock, which are formed by lava that comes out of the earths crust, then cools and solidifies rapidly on the earths surface due to exposure to the environmental atmosphere.
Rock formed from lava is extrusive igneous rock.
Basalt is the igneous rock formed when lava cools at the Earth's surface. It is fine-grained and commonly found in ocean basins.
Two igneous rocks formed by fast cooling lava are basalt, which is a fine-grained volcanic rock, and obsidian, which is a natural glass formed from rapidly cooling lava without crystal growth.
Igneous rocks are formed when lava cools. After a eruption, the lava cools, and the igneous rock is formed.
Intrusive igneous rocks are thusly formed.
igneous rock is formed when lava cools down
Igneous rock is formed from solidified and cooled magma or lava.
Igneous rock is formed from lava that has cooled and, of course, hardened.
the type of rock formed when lava or magma cools is igneous rock..
Igneous rock, specifically basalt, is formed when lava cools quickly. Basalt is characterized by its fine-grained texture due to rapid cooling at the Earth's surface.
Uplift and solidification
Extrusive igneous rock is formed from rapidly cooling lava.
