100

Does this mineral show cleavage or fracture?

Cleavage, smooth flat breaks

100

What is the difference between extrusive and intrusive igneous rocks? (where, cooling, crystals)

Extrusive rocks form on the surface, cool quickly and have small crystals.

Intrusive rocks form underground, cool slowly, have large crystals.

100

What are the factors that contribute to metamorphism

Temperature and Pressure

100

What are the three types of sedimentary rocks?

Clastic (sediments), 

Crystalline (chemical), 

Bioclastic (dead plants/animals)

100

Describe the differences between the continuous and discontinuous series on Bowen's reaction series  

Discontinuous changes the mineral as the temp cools but the continuous mineral stays plagioclase as it cools.

200

Describe the luster of this mineral.

Nonmetallic; specifically earthy or dull

200

Which igneous rock is more dense. Felsic or Mafic

Mafic rocks

200

What geological process will form REGIONAL metamorphism

Plate tectonics

200

What is the processes are involved for a clastic rock to form?

Weathering and Erosion, Deposition, Burial, Compaction, lastly Cementation

200

Using the reference table, describe with the appropriate terms (rock cycle processes), how a rock moves from magma to a sedimentary rock.

Magma cools into an igneous rock, then is *probably uplifted*, weathered and eroded into sediments, deposited, and finally compacted or cemented into a sedimentary rock.

300

Name two of the six special characteristics that can be used to identify minerals.

Odd texture, smell, fluorescence, fizzes with acid, taste, magnetism

300

What does it mean to have vesicular texture?

It has holes/gas pockets

300

What is banding in metamorphic rocks?

Alternating layers of light and dark.

300

What do bioclastic (organic) rocks form from?

Once living things, like animals and plants.

300

What ELEMENTS are common in felsic rocks and mafic rocks

Felsic- Silicon, Potassium and Sodium

Mafic- Iron, Magnesium and Calcium

400

Why do minerals form in specific shapes. For example. why does micas form in a "platy" shape or pyrite in a cubic shape?

Their chemical composition aligns them in a specific way, not randomly.

400

Hurrah! Bonus points for you!

Enjoy

400

Which metamorphism occurs when lava squeezes through bedrock as it frees itself from the mantle?

Contact Metamorphism

400

Name any sedimentary rock that can be chemically formed (crystalline)

Rock Salt, Rock Gypsum, Limestone, Dolostone, Chert

400

What kind of minerals can be found in diorite?

Quartz, Plagioclase feldspar, Muscovite, Biotite, Amphibole and Pyroxene.

500

Using the reference table, name a special characteristic of the mineral Talc

Soapy feel, VERY soft.

500

What processes form an igneous rock? (rock cycle terms!)

Melting, Cooling and solidifying, Outgassing/volcanism

500

What is the difference between foliated and non-foliated rocks?

A foliated metamorphic rock has a visible layered or banded appearance due to the alignment of minerals under pressure, while a non-foliated metamorphic rock lacks this layered structure and has a more uniform texture

500

What differentiates clastic rocks from one another?

The size of the clast. i.e conglomerate=cobbles, sandstone=sand, shale=clay

500

Using the reference table, describe what needs to occur before crystalline sedimentary rocks form.

Gasses and salts dissolve in solution and minerals precipitate down. The water will evaporate away then lithification happens
