                                 Rocks  Worksheet  Answers  

 Questions      1.    What  is  the  difference  between  rocks  and  minerals?    Rocks  are  made  of  different  minerals.    Minerals  are  the  ingredients  for  rocks.  

 2.    How  many  types  of  rocks  make  up  the  Earth’s  crust?  Three    

 3.    What  are  the  names  of  the  3  types  of  rocks?  Igneous,  Metamorphic,  &  Sedimentary  

 4.    How  are  igneous  rocks  formed?  As  molten  rock  cools  and  hardens  the  minerals  crystallize  and  form  igneous  rocks.  

 5.    What  is  another  name  for  igneous  rocks?  Rocks  of  fire  

 6.    What  is  the  difference  between  the  two  types  of  igneous  rocks?  Extrusive  igneous  rock  forms  when  molten  rock  comes  to  the  surface  (lava)  and  cools  quickly  to  produce  fine-­‐grained  rocks.  

 Intrusive  igneous  rock  forms  when  molten  rock  solidifies  underground  and  cools  slowly  to  produce  coarse-­‐grained  rocks.  

         7.    How  are  sedimentary  rocks  made?      When  sediment  or  bits  of  rock  plus  materials  such  as  shells  and  sand  get  packed  together.  

       8.    How  are  metamorphic  rocks  made?  Deep  in  the  Earth  by  heat  and  pressure  caused  by  processes  such  as  mountain  building.  

 9.    What  does  the  word  “metamorphosis”  mean?  To  change  

       10.    Which  two  layers  of  the  Earth  are  made  of  rock?      Crust  =  solid  rock      Mantle  =  molten  rock/magma  

 11.    What  are  the  names  of  the  other  two  layers  of  the  Earth,  and  what  are  they  made  of?  

Inner  and  Outer  Core,  both  are  made  of  iron.    12.    Write  the  following  layers  of  the  earth  in  order  from  most  dense  to  least  dense:  atmosphere,  

crust,  inner  core,  mantle,  outer  core,  water.          Inner  Core,  Outer  Core,  Mantle,  Crust,  Water,  Atmosphere
