Rocks and minerals - British Geological Survey
Igneous rocks. The word 'igneous' comes from the Latin word ignis, meaning fire. At plate boundaries, or hot spots, some rocks get heated deep inside the Earth and melt into 'molten rock'. Molten rock is called magma when it is inside the Earth and lava when it is on the surface. As it cools, it crystallises and solidifies to form igneous rock.
