Porphyritic
Igneous rocks look different depending on how fast the magma cools.
You say it as ' Igneous ROCK ' and ask whether it is a rock..
Igneous rocks are formed through the solidification of molten rock material called magma or lava. Magma cools and solidifies either beneath the earth's surface, forming intrusive igneous rocks, or at the surface, forming extrusive igneous rocks. These rocks are characterized by a crystalline structure and can include minerals like quartz, feldspar, and mica.
Magma underground may differentiate and form different intrusive igneous rock. Magma from the magma body may erupt, cool, quickly, and form fine-grained extrusive igneous rock, or partially remain underground and form intrusive igneous rock. The type of igneous rock formed from the magma body will largely depend on whether or not it is erupted, and the speed of its cooling.
The igneous texture characterized by two distinctively different crystal sizes is known as porphyritic texture. Porphyritic rocks have larger crystals (phenocrysts) surrounded by a fine-grained matrix (groundmass), indicating two different stages of cooling within the magma.

Pumice is a type of igneous rock formed from volcanic eruptions. It is characterized by its porous and lightweight nature, caused by the rapid cooling of lava during volcanic explosions, which traps gas bubbles in the rock.
No. Igneous, sedimentary, and metamorphic rocks are three different categories of rock.
Intrusive igneous rocks are characterized by a coarse-grained texture because they cool slowly beneath the Earth's surface, allowing larger mineral crystals to form. This slow cooling process gives the minerals more time to grow, resulting in a coarse-grained appearance.
there's a Latin word called "igneus" which means fire and the igneous rock is formed by lava, but that's a different subject.

Igneous rocks, which come in many different forms.
Igneous rocks vary greatly in composition and method of formation, resulting in diverse densities.
