What is an extrusive igneous rock ?

• An extrusive igneous rock is formed from organic matter that undergoes fossilization
• An extrusive igneous rock is formed from sedimentary rock that undergoes intense heat and pressure
• An extrusive igneous rock is formed from magma that cools slowly beneath the Earth's surface
