Rock Cycle
1. What are the three main types of rocks?
The three main types are sedimentary, metamorphic, and igneous and the differences among them have to do with how they are formed.
2. How does a sedimentary rock turn into a metamorphic rock?
The Heat and pressure cause minerals in the rock to re-crystallize, and sometimes interact with each other causing the rock to metamorphose.
3. How does an igneous rock turn into a metamorphic rock?
Its caused from weathering and erosion, sediment, compactions and cementation to form the metamorphic rocks
4. How do metamorphic rocks change into sedimentary rocks?
Metamorphic rock must first turn into sediment through uplift, weathering, erosion and deposition before the sediments can undergo lithification and become sedimentary rock.
5. How do igneous rocks change into sedimentary rocks?
Sedimentary rock to change to Igneous rock by applying heat and pressure , which creates Metamorphic rock . Next , Metamorphic rock turns to Magma because it melts .
6. What is the beginning of the rock cycle? The end?
Sedimentary rock to change to Igneous rock by applying heat and pressure , which creates Metamorphic rock . Next , Metamorphic rock turns to Magma because it melts .

7. Quick cooling forms many small what?
Crystals
8. When you look at the desert monuments, what eroded away?
The sandstone eroded away
9. The microscopic view of sandstone contains what two components?
They contain sand grains and cement.
10. What two things are needed to turn igneous rock into metamorphic rock?
Lots of heat and pressure.
Rocks
11. List and define the 6 key characteristics that can help you identify rocks within the three main classes.
Crystals
Small, flat surfaces that are shiny or sparkly, like tiny mirrors.
Fossils
Imprints of leaves, shells, insects, or other items in the rock.
Gas bubbles
"Holes," like Swiss cheese, in the rock.
Glassy surface
A shiny and smooth surface, like colored glass.
Ribbonlike layers
Straight or wavy stripes of different colors in the rock.
Sand or pebbles
Individual stones, pebbles, or sand grains visible in the rock

Rock Identification Key
12. For igneous rock, when magma cools slowly the crystals…
the crystals are large enough to see.
13. For igneous rock, when magma cools quickly, the crystals…
the crystals are very small, and microscopes are required to see them.
14. Of the types of igneous rock formed underground, which one is most familiar?
Granite, is the most familiar for me.
15. When looking at sedimentary particle size, which material type has the largest particles and which has the smallest particles?
16. Which metamorphic rock forms under the highest temperature and highest pressure?
Sedimentary rock to change to Igneous rock by applying heat and pressure , which creates Metamorphic rock . Next , Metamorphic rock turns to Magma because it melts .
Sand has the largest particles while clay has the smallest.
6. What is the beginning of the rock cycle? The end?
Gneiss formed with the highest pressure and temperature.
