As the super hot magma cools, it solidifies to form a rock and that rock is called igneous rock. When most people think of igneous rock they vision a volcano erupting pumice and lava. Igneous rocks form directly by crystallization from materials from a magma melt.
Background: The term igneous comes from the Latin ignis, meaning fire. Igneous is used to describe rocks that crystallize out of hot molten material in the Earth called magma. When magma pushes up through Earth's crust to the surface, it is called lava.Both magma and lava cool and harden to form igneous rocks.ackground: The term igneous comes from the Latin ignis, meaning fire.
