rock cycle
100
this mineral has a hardness of about 3, rhomobohedral cleavage, and fizzes when acid is dropped on it
What is calcite
100
the different between lava and magma
What is lava-above ground, magam-underground
100
these a particles or fragments of pre-existing rocks that form from weathering.
What are sediments
100
this is what causes metamorphic rocks to form
What is heat and pressure
100
type of rock that comes from molten (melted) rock.
What is igneous
200
an example of a fine-grained, dense, darkly colored rock.
What is basalt
200
these types of sedimentary rocks are made up of things that were once alive.
What are organic
200
this type of metamorphism happens over large areas. Like mountain building events
What is regional
200
type of rocks that form from heat and pressure
What is metamorphic
300
this characteristic can be tested using things like a penny, a class plate, and your fingernail
What is hardness
300
felsic igneous rocks tend to be dark or light colored?
What is light
300
rock salt is an example of this type of sedimentary rock
What is chemical
300
this type of metamorphism occurs in smaller areas, sometimes when rocks get 'cooked' due to being close to a hot igneous intrusion
What is contact
300
type of rock that forms from the compaction and cementation of rock fragments.
What is sedimentary
400
these are the two ways in which a mineral breaks. Either in a nice repeating pattern or not.
What is cleavage and fracture
400
an intrusive igneous rock will have this type of texture
What is coarse-grained
400
these are imprints that can be found in sedimentary rocks of plants, animals, or other things.
What are fossils
400
this foliated metamorphic rock shows banding
What is gneiss
400
what types of rocks and metamorphic rocks be made from?
What is any
500
state the 4 criteria something must have in order ot be classified as a mineral
What is solid, inorganic, naturally occurring, definite structure and composition
500
pumice and scoria have this type of texture due to gas pockets trapped in them.
What is vesicular
500
this group of minerals makes up the majority of all the minerals in the world
What is the silicates
500
this is what shale turns into when it is metamorphosed
What is slate
