magma
No. Magma and lava are molten rock. When the cool they form igneous rock.
Lava.
Extrusive igneous rock is formed from rapidly cooled lava at Earth's surface. Examples are obsidian and basalt.
Lava is, by preferred definition, a viscous fluid comprised of molten rock that has reached the surface. In this case, lava is not an igneous rock. However, 'lava' can also refer to the cooled and solidified product of the molten rock. In this case, lava is an igneous rock, formed from the solidification of molten lava.
Once magma and lava cool and harden, they solidify to form igneous rocks. The texture and composition of the rocks depend on the cooling rate and mineral content. Over time, these rocks can be uplifted, eroded, and transformed in the Earth's crust through various geological processes.
Igneous rocks.
magma cools into intrusive igneous rock while lava into extrusive igneous rock
Igneous rock forms from the cooling of molten material called magma or lava.

Igneous rocks
Igneous rocks that result from lava solidifying above ground are classified as extrusive igneous rocks. These rocks cool quickly, leading to small mineral grains and a fine-grained texture. Examples include basalt and rhyolite.
Lava.
Metamorphic rocks become igneous rocks by melting from heat and pressure, remnants of which may cool from melt (magma) and become components of igneous rock.

The minerals in magma form crystals when solidifying, giving igneous rocks their characteristic hardness.
Lava flows cool rapidly compared to the cooling of rocks underground. The slower cooling time of intrusive igneous rocks allows larger crystal formation. Generally, the more cooling time, the larger the crystals.
