Rock Properties
Crystals that take longer to cool are bigger or smaller than those that less time to cool?
bigger
What type of rock is the crystallization of magma
Igneous Rock
Which type of rock will have air pockets?
Igneous
Anything with the word acid will be what type of weathering?
Chemical
What happens first, weathering or erosion?
Weathering
comparing sugar to kosher salt which one is coarser, which one is finer
kosher salt - coarser
sugar - finer
What do the following proccesses give you?
Melting , Weathering and Erosion, Heat and Pressure
Melting - Magma
Weathering and Erosion - Sediment
Heat and Pressure - Metamorphic Rock
Which type of rock will have fossils?
Sedimentary
Rust forming on rocks containing iron is an example of which type of weathering?
Chemical Weathering
What is the difference betwen weathering and erosion
Weathering is breaking down into sediment
Erosion is sediment being carried away
What is the difference between intrusive and extrusive and which type of rock does it apply to?
Intrustive - made inside the Earth
Extrusive - made on Earth's surface
Igneous
Is the rock cycle linear, give an example?
No it is not, igneous rock can become either metamporhic (add heat and pressure) or sediment (weathering and erosion) proving that there are different paths and things do not always happen in the same order
Which type of rock can be identified by its glassy appearance?
Igneous
What is it called when something weathers something else by rubbing and scraping against each other
Abrasion
Show me an example of mechanical weathering without making a mess
Anything where you are wearing or physically breaking something to make it smaller
What is the difference between layers and bands and which rock has which?
layers - usually mostly flat and different layers of sediement for sedimentary rock
bands - usually black and white and usually curved and morphed due to the addition of heat and pressure of metamporhic rock
Each rock has a specific process which leads to that rock what are the processes?
Crystallization - Igneous
Heat and Pressure - Metamorphic
Compaction and Cementation - Sedimentary
What are the five steps that make Sedimentary Rocks
Weathering
Erosion
Deposition
Compaction
Cementation
Explain frost wedging in your own words?
The continual cracking of rock, by water getting into the cracks freezing and expanding then melting deeper into the cracks and starting the process all over again
What kind of rock reminds you of your Science teacher
