The type of rock produced by the cooling and solidification of molten rock is called igneous rock.

Here's a breakdown:

* Magma: Molten rock found beneath the Earth's surface.

* Lava: Molten rock that has erupted onto the Earth's surface.

* Igneous Rock: Formed when magma or lava cools and solidifies.

There are two main types of igneous rocks:

* Intrusive igneous rocks: Formed from magma that cools and solidifies beneath the Earth's surface. These rocks tend to have larger crystals because they cool slowly.

* Extrusive igneous rocks: Formed from lava that cools and solidifies on the Earth's surface. These rocks tend to have smaller crystals because they cool quickly.
