3. Igneous Rock!!  Igneous can be internal or exposal.  Igneous is formed by lava/magma.  Igneous mean’s fire made.

4. More Igneous Rock!!! Igneous has 3 main rock groups: Basalt,Granite,and Obsidian.

5. Granite, Obsidian, And Basalt!!!  Obsidian has a glassy look to it.  Basalt has a fine grained to it.  Granite is a coarse-grained rock.

6. Sedimentary Rock!!  Sedimentary has nine rocks that I know of.  Rock salt, shale, limestone, conglomerate, chert, arkoses, and sandstone.  Sedimentary is mostly found in layers.  Sedimentary means sand glued together.

7. More Sedimentary Rock!!! Conglomerate has a cement look to it. And looks like it had rock stomped to it. Rock salt haves a clear look to it. Sandstone looks like it has sand glue to it. And it has a tan look to it. Shale has a dark gray to it. Pulse it looks like it is a layer to it. Limestone has a gray color. Pulse it looks like it has rice in it.

8. Metamorphic Rock!!  Metamorphic changes by heat, pressure, and chemical changes.  I know three metamorphic rocks: quartzite, gneiss, and marble.  Metamorphic means change in form.

9. More Metamorphic Rock!!!  The pressure is from the layers above it.  The heat is from magma.  Metamorphic always formed by a different rock, just have to go thought all the steps first.

10. Minerals!  I know lots of minerals: Diamonds, Galena, Pyrite, Talc, Mica, Feldspar, Quartz, Hornblende and lots more!  Every rock has to have minerals made up of it.  Are naturally occurring substances.

11. More Minerals!!  The softest mineral is talc.  The second closest to the middle is pyrite.  Closest to the middle is galena.  The hardest mineral is diamond.

12. The Rock Cycle!!!  Now we start off with sandstone!  Quartzite too!  Lava’s next!  Then basalt! Then ends on a dirt hill!  Then goes back around!  The rock cycle never ends.

13. Creates!!!!! People (or things) helped me on my power point.  Science Book!!!  Google!  Mr. Landon!!!!  Christian Andsager!!!!!!!  Microsoft Power Point 2007!!!!! The End! Hoped you enjoyed!!!!
