1. Sedimentary, Igneous & Metamorphic Rock

2. Sedimentary Rock What is it made up of? How is it formed (process)?
Sand, clay, silt, organic matter (fossils)
How is it formed (process)?
Weathering (wind, flowing water, ice, living organisms) create sediment
Erosion moves/transports the sediment (water, wind etc.)
Deposition – sediment is deposited at the bottom of bodies of water
Cementation/lithification – the layers are pressed together (cemented) to form rock

3. Where are sedimentary rocks formed?
At the bottoms of lakes, rivers, oceans, streams…
Examples:
Sandstone, limestone, shale
Sedimentary rocks are used For:
Buildings, statues

4. Metamorphic Rock What is it made up of? How is it formed (process)?
Previous sedimentary and igneous rock
MAY HAVE fossils
Contain layers which look like wavy bands
Hardest rock
How is it formed (process)?
Extreme heat and pressure due to the movement of the Earth’s crust

5. Where are Metamorphic rocks formed? Underground in hot temperatures
Examples:
Slate and marble
Metamorphic rocks are used for:
Countertops, chalkboards, roof shingles, floors

6. Igneous Rock What is it made up of? How is it formed (process)?
Previous sedimentary and metamorphic rock
Intrusive igneous rock- cooled magma
Extrusive igneous rock-cooled lava
How is it formed (process)?
When magma and lava cools and hardens
Intrusive – cools slowly and forms large crystals
Extrusive – cools quickly and forms small crystals or none at all

7. Where are Igneous rocks formed?
Intrusive igneous rock is formed
from magma below ground.
Extrusive igneous rock is formed
from lava above ground.
Examples:
Intrusive – granite
Extrusive - obsidian and pumice
Igneous rocks are used for:
Intrusive - buildings, countertops, statues
Extrusive - arrow heads, sharp blades
