CLUES FROM IGNEOUS
ROCK
❖ Lava that hardens on the surface
and forms igneous rock is called
an extrusion.
❖ An extrusion is always younger
than the rocks below it.
❖ When magma cools and hardens
into a mass of igneous rock
beneath the surface, it is called an
intrusion.
❖ An intrusion is always younger
than the rock layers around and
beneath it.
