<h3>What is igneous rock? </h3>
Igneous rocks create when lava colds and crystallizes, either on the boundary of the Earth or heavy inside the crust.
Because of the high heat present underneath, all magma forms in the lower crust or upper mantle.
A mineral crystal's radiometric age in an igneous rock indicates how long it has been since the atoms within the crystal were part of a molten magma body.
