When molten magma cools and crystallizes, it becomes a hard rock called igneous rock. Different magmas have different compositions and so produce different igneous rocks.
If the magma cools beneath the earth's surface, it cools slowly. Rocks formed like this are called intrusive rocks, and have large crystals, e.g. granite, gabbro, dolerite.
If magma comes to the surface (in a volcanic eruption) it cools rapidly. Rocks formed like this are called extrusive rocks, and they have small crystals, e.g. basalt, obsidian, pumice.
Igneous rocks have interlocking mineral crystals. The crystals are arranged randomly throughout the rock. Igneous rocks are mostly non-porous.

rock is melted to form molten rock, then as the lava hardens, it forms any type of igneous rock
Granite is formed from molten rock that has cooled. Since it forms underground, however, the molten rock that it forms from is called magma rather than lava.

the type of rock formed when lava or magma cools is igneous rock..
Basically, all types of Volcanoes. Molten Rock, also called Lava, and Magma are Igneous Rock. They are the rock that comes out of an erupting Volcano.

They're igneous rocks, as they are formed from molten magma/ lava

Molten rock
An igneous rock is a rock formed by the solidification of molten lava. some examples of this rock type are: Pumice, Obsidian, Basalt, Andesite, and Ryholite.
Lava IS molten rock therefore your question is meaningless.

When molten rock solidifies it forms igneous rock.
Pumice
Ignious rock
