Extrusive igneous rock is formed from rapidly cooling lava.
Extrusive igneous rock is formed from the crystallization of minerals as the lava cools.
the type of rock formed when lava or magma cools is 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.
When lava cools down quickly at the surface of the Earth, it forms an igneous rock called basalt. Basalt is dark in color, fine-grained, and contains minerals such as olivine and pyroxene.
Igneous rocks are formed when molten magma cools and solidifies either beneath the Earth's surface (intrusive) or on the surface (extrusive). Intrusive igneous rocks are formed from magma that cools slowly underground, while extrusive igneous rocks are formed from lava that cools quickly on the surface.
Igneous rock is formed.
pumice
Igneous rocks are formed when lava cools. After a eruption, the lava cools, and the igneous rock is formed.
Extrusive igneous rock is formed from the crystallization of minerals as the lava cools.
Igneous rock is formed through the cooling and solidificatio of magma or lava.
Pumice
Pumice rock.
When lava cools and solidifies.
metamorphic rocks
When lava cools it forms extrusive igneous rock.
it is lava and when lava cools it forms igneous rock
fast cooling lava -small crystals or no crystals
