Minerals
When a mineral breaks along a smooth, flat surface.
What is cleavage?
All rocks are made up from these.
What are minerals?
Granite is this type of igneous rock.
What is intrusive?
This means to change.
What is morph?
Difference between conglomerate and breccia.
What is fragment shape? (Not size)
The mineral has a reaction when it comes into contact with hydrofluoric acid.
What is calcite?
The edible food lab we did represent this type of rock.
What is sedimentary?
This must occur to form igneous rocks.
What is heating and cooling of magma?
This must occur in order to form metamorphic rocks.
What is heat and/or pressure?
A rock that is made from the decomposition of plants in a swamp environment.
What is coal?
What is naturally occurring, inorganic solid with definite chemical composition and orderly arrangement of atoms?
What is a mineral?
Coquina is this type of rock.
What is sedimentary?
Two types of igneous rocks.
What is intrusive and extrusive?
Metamorphic rocks were once these.
What are sedimentary and igneous rocks?
This must happen for sedimentary rocks to form.
What is compaction and cementation?
Atom arranged in a pattern that is repeated over and over again.
What is crystalline?
These two types of rocks form in layers.
What is sedimentary and metamorphic?
Intrusive rocks always have these larger than extrusive rocks.
What is larger crystals?
This is when a rock has thin, wavy lines of crystals throughout the rock.
What is foliated?
Loose materials such as mineral grains and rock fragments caused by weathering and erosion.
What are sediments?
Two characteristics that are true for all minerals.
What is a mineral formed by all natural processes, is inorganic, solid, chemical composition, and has a crystal structure?
These two types of rocks need high temperatures to form.
What is igneous and metamorphic?
Pumice, obsidian, and scoria are all examples of this.
What is volcanic glass?
This rock forms from granite, but under extreme heat and pressure and is foliated.
What is Gneiss?
Three types of sedimentary rocks.
What are organic, detrital and chemical?
