1. Rocks of our Earth

2. Which layer are we living on?
On the continents on part of/top of the CRUST
Crust made of ROCKS. (the crust rocks!)
Land/ Ground= a Lot of Granite
Ocean floor = a lot of basalt

3. TYPES OF ROCKS Igneous Sedimentary Metamorphic
3 major groups named for how they are FORMED
Igneous
Sedimentary
Metamorphic

4. IGNEOUS ROCKS Formed from cooling of molten material Lava (land) Ash
Magma (mantle)

5. TYPES OF IGNEOUS ROCKS BASALT GRANITE (Lava formed)
Most common igneous rx
(Magma formed)

6. SEDIMENTARY ROCKS Sediments: Pebbles Sand & silt Clay Shells & bones
Made of layers of sediments that have been pressed or cemented together
Sediments:
Pebbles
Sand & silt
Clay
Shells & bones
Sediments deposited by wind & water

7. TYPES OF SEDIMENTARY ROCKS
Shale
Coal
Limestone
forms mainly from plant debris
composed of calcium carbonate.
Forms from the accumulation of shell, coral, algal & fecal debris
Sandstone

8. METAMORPHIC ROCKS changed by intense heat & pressure inside Earth
“Meta” ~ means change (Greek)
“Morphosis” ~ means form (Greek)
changed by intense heat & pressure inside Earth
Igneous, sedimentary, & even metamorphic rocks can be changed into different metamorphic rocks

9. TYPES OF METAMORPHIC ROCKS
SLATE
MARBLE

10. ROCK CYCLE The rock cycle is a never-ending process of rocks: *forming
*weathering
*changing into other rocks

11. Anything can happen in the Rock Cycle
Type of Rock
What Happens??
New Rock Formed
igneous
subjected to heat & pressure
metamorphic
re-melted
sedimentary 
weathered & eroded
sedimentary
heated enough to melt
weathered and eroded
