No, igneous rocks can form both beneath and above the Earth's surface. Intrusive igneous rocks form beneath the surface as magma cools and solidifies underground. Extrusive igneous rocks, on the other hand, form on the Earth's surface when lava cools and solidifies quickly.
The Igneous rock formed when magma cools are; 1. Extrusive (Volcanic) Igneous Rock; which are igneous rocks formed when magma cools outside the earths crust. The texture of of extrusive igneous rock is fine grained. 2. Intrusive (Plutonic) Igneous Rock; these are igneous rocks formed by gradual cooling of magma within the earths crust. The texture is coarse grained.

Some do. These are called extrusive igneous rocks. However a large portion of igneous rocks form beneath the surface. These are intrusive igneous rocks.
The substance that cools beneath the earths surface when an intrusive igneous rock forms is Magma. Magma is a molten material made up of rocks and minerals.

Intrusive igneous rocks form beneath Earth's surface as magma cools and solidifies slowly within the crust. These rocks have large mineral grains due to the slow cooling process, which allows time for crystals to grow. Examples include granite, diorite, and gabbro.

Volcanic (Extrusive) igneous rock, which are formed by lava that comes out of the earths crust, then cools and solidifies rapidly on the earths surface due to exposure to the environmental atmosphere.
