100

Which is more reliable at identifying minerals: streak or color?

Streak

100

This mineral is clear, has a cubic form, and is commonly known as table salt (NaCl).

Halite

100

What does intrusive mean?

Cooled within the Earth

100

What does foliated mean in the context of metamorphic rocks?

Parallel alignment of minerals, forming a layered texture

100

What are the 3 types of sedimentary rocks?

Chemical, clastic, and biogenic

200

What does foliated mean?

The mineral is sheet-like

200

This mineral is black, foliated, and has perfect basal cleavage.

Biotite

200

If a rock is plutonic, does that mean that it is intrusive or extrusive?

Intrusive

200

What is the parent rock of gneiss, schist, and slate?

Mudstone

200

What type of sedimentary rock is coal?

Biogenic

300

Name the four tools we used to test a mineral's hardness.

Fingernail, penny, glass plate, metal nail

300

This mineral is cubic or massive, brassy yellow, and commonly known as "fool's gold."

Pyrite

300
What is the exception to the rule that felsic means that a rock is light?

Obsidian

300

What is California's state rock?

Serpentinite

300

What is lithification?

Compaction of sediments creates a new rock

400

What is the difference between cleavage and fracture?

Cleavage leaves a well-defined break whereas fracture has no uniform way of breaking

Marble

400

How are clastic rocks classified?

Grain size, grain shape, and mineralogy

500

What is a mineral? Hint: there are 5 components.

Options: inorganic, solid, naturally occurring, definite chemical composition, structured atomic arrangement

500

This mineral can either be a shiny/silvery black or a rusty red color, but it will always have a reddish brown streak.

Hematite

500

Define porphyritic.

Igneous rocks with large crystals set in a background of smaller/non-visible crystals

500
What 3 factors influence the type of metamorphic rock formed?

Parent rock, temperature, and pressure

500

Name 2 of the depositional environments for mudstone.

Options: deep marine, shelf/platform, tidal flats, and lakes
