Igneous Rocks Igneous means Fire in Latin Many are produced by Volcanos Some are produced when underground magma cools and hardens
Igneous Rocks being formed
Sedimentary Rocks When little pieces of rock and other sediments are broken down by erosion or wind, they are carried down creeks and rivers and settle. They are then cemented and compacted over time. Can take thousands to millions of years
Sedimentary Rocks taken shape
Metamorphic Rock Metamorphic rocks were once igneous and sedimentary rocks. So, how did they turn into metamorphic rocks? Tons and tons of pressure, which causes heat build up and change occurs.
The Rock Cycle
Sedimentary Rocks Sedimentary rocks are the most abundant rock type on Earth 99% of all rocks in Kentucky
Coal is a very common sedimentary rock formed from plant material (peat and ferns).
the sedimentary rock limestone will become the metamorphic rock marble
the sedimentary rock shale will become the metamorphic rock slate
the igneous rock granite will become the metamorphic rock gneiss (pronounced nice).
Igenous Rocks Used for Statues Construction Cleaning supplies
Sedimentary Rock Was used to build the Whitehouse Used in cement
Metamorphic Rock Used for: Buildings Floors Chalkboards
