Igneous rocks are formed when molten rock (magma) is pushed up from beneath the earth’s crust and cools to form solid rock
The molten rock is called lava when it reaches the surface They contain crystals and are very hard.
There are two types of igneous rock Intrusive (cools within the earth) Extrusive (cools outside the earth).
