WEATHERING
100
This rock has large crystals surrounded by smaller crystals.
What is porphyry?
100
Foliated rocks are created by these 2 processes.
What are erosion and deposition?
100
This is where most metamorphic rock forms.
Where is deep underground?
100
Forces from here drive the rock cycle.
Where is deep inside Earth?
100
This is the grinding away of rock by other rock particles carried by wind, water, or ice.
What is abrasion?
200
This is the most common extrusive rock.
What is basalt?
200
Coal is an example of this kind of rock.
What is an organic rock?
200
These rocks have their grains arranged in parallel bands.
What is foliated?
200
When igneous rocks erode they can become this.
What are sedimentary rocks?
200
This is how plants weather rocks.
What is they produce a weak acid around their roots?
300
This is why igneous rocks have large crystals.
What is they cooled slowly?
300
This type of rock forms when minerals that are dissolved in a solution crystallize on Earth's surface?
What are chemical rocks?
300
Slate came from this rock.
What is shale?
300
When sedimentary rocks undergo heat and pressure they can become this type of rock.
What is metamorphic rock?
300
This is the movement of rock particles by wind, water, ice, or gravity.
What is erosion?
400
This is the source of igneous rocks.
What is magma?
400
This is the process of dissolved materials crystallizing and gluing particles of sediment together.
What is cementation?
400
These are the two forces that can change rocks into metamorphic rocks.
What are heat and pressure?
400
When metamorphic rocks melt they can become this.
What are igneous rocks?
400
This is when a material contains air spaces that allow water to seep through.
What is permeable?
500
This is Earth's most abundant igneous rock, popular because of its durability.
What is granite?
500
This is the process that presses sediments together.
What is compaction?
500
This is how geologists classify metamorphic rocks.
What is by the arrangement of the grains in the rock.
500
When metamorphic rocks erode they can become this.
What are sedimentary rocks?
500
This is the most important agent of chemical weathering.
What is water?
