Igneous Rock-Intrusive/Extrusive              
                Interusive- Igneous Rocks form inside of the volcano and has a big crystals.

       Extructive- Igneous Rocks form outside of the volcano and has a small crystals

 

 
Sedimentary Rocks-Clastic/Crystalline/Bioclastic
                 Clastic-Broken pieces of rock
                                    

                           Crystalline-Evaporation of liquid（under water).

             Bioclastic-Made from dead or ganisms(coal）
