Igneous Rocks. Igneous rocks (fiery rocks) are made when molten material inside or outside the earth cools and becomes solid. This melted rock is called magma when it is inside the earth. When magma finds its way to the surface through cracks or volcanoes, it is called lava. When lava cools on top of the earth’s surface, it forms extrusive

:Rocks vs MineralsMinerals Found in RocksRocks are aggregates of one or more minerals, mineraloids, and organic components. Rocks may form when minerals grow ( crystallize) together, forming a crystalline rock, such as the granite shown above. They also can form when loose grains are cemented together, forming a clastic rock, such as sandstone. Crystalline rocks may form from a magma
