1 Igneous Rocks Igneous means Fire in Latin Many are produced by Volcanos Some are produced when underground magma cools and hardens

2 Igneous Rocks being formed

3 Basalt

4 Granite

5 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

6 Sedimentary Rocks taken shape

7 Sandstone

8 Limestone

9 Coal

10 Shale

11 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.

12 Metamorphic Rocks

13 Slate

14 Marble

15 The Rock Cycle

16 Sedimentary Rocks Sedimentary rocks are the most abundant rock type on Earth 99% of all rocks in Kentucky

17 Coal is a very common sedimentary rock formed from plant material (peat and ferns).

18 the sedimentary rock limestone will become the metamorphic rock marble

19 the sedimentary rock shale will become the metamorphic rock slate

20 the igneous rock granite will become the metamorphic rock gneiss (pronounced nice).

21 Igenous Rocks Used for Statues Construction Cleaning supplies

22 Sedimentary Rock Was used to build the Whitehouse Used in cement

23 Metamorphic Rock Used for: Buildings Floors Chalkboards

24 Stalactites

25

26 Stalagmites
