The lava cools.
Yes, when lava cools and solidifies, it forms igneous rock. The type of rock that forms depends on the chemical composition of the lava and the rate at which it cools.
When lava cools it forms extrusive igneous rock.
The rock that forms from the cooling of lava is called igneous rock. When lava cools and solidifies on the Earth's surface, it is specifically referred to as extrusive igneous rock, such as basalt. If the lava cools slowly beneath the surface, it forms intrusive igneous rock, like granite.
Yes, an igneous rock forms when lava is cooled. It is called an extrusive igneous rock (because lava is extruded onto the surface of the earth). A magma pool that did not erupt as lava can cool to become an intrusive rock.
The igneous rock forms from lava because when a volcano erupts the lava that flows from a volcano. Igneous rocks have a hot liquid in the beginning. The lava that flows forms into an igneous rock fast. When the lava reaches the surface, it cools rapidly and turns into igneous rock.

Lava will cool to form extrusive igneous rock. The exact type would depend on the composition of the lava.
Cooled lava forms extrusive igneous rock, such as rhyolite, basalt, obsidian, and pumice.
