Igneous Rocks

Igneous Rocks. Igneous Rock Formation. Igneous rock: forms when lava or magma cools and minerals crystalize Magma : molten rock below the Earth’s surface Lava : is magma that flows out onto the Earth’s surface The type of igneous rock that forms depends on the composition of the magma.
