A trip to a volcano quickly reveals that lava quickly "freezes" into something that seems like rock. Examination of rock around the volcano (bottom left) shows it to be made of very small mineral crystals. Other rocks coughed up from deep within the volcano (bottom right) show mosaics of larger crystals and banded structures.
