Rocks formed by the cooling and solidifying of molten materials.
Volcanic rock is igneous, not sedimentary or metamorphic. It forms when magma cools and solidifies on or near the Earth's surface. Sedimentary rocks form through the accumulation and cementation of sediments, while metamorphic rocks form from the alteration of existing rocks due to heat and pressure.
An intrusive igneous rock.

Igneous rock. Extrusive igneous rock forms at or near the surface, intrusive igneous rock forms below the surface.
The melting of metamorphic or igneous rock forms magma.
Yes.By definition, igneous rock forms from molten rock.
Yes. By definition a rock is solid.
They are both formed from the solidification of magma, the definition of igneous rock.

Igneous rock. the definition of igneous: Formed by solidification from a molten state.
Igneous rock is a type of rock that forms from the cooling and solidification of magma or lava. It is classified based on its texture (coarse or fine-grained) and composition (silica content and mineralogy). Examples include granite, basalt, and obsidian.
Rhyolite is an igneous, black volcanic rock.
No. If a rock melts and then re-solidifies, then by definition the resulting rock is igneous.
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.
Because that is the very definition of igneous rock.
Cooling in the rock cycle means when the rock for example: Igneous rock is transforming it needs to cool when its first magma
Igneous rock is formed.
