Rocks in General
What is any naturally occurring solid mass made up of minerals?
A rock
How are Igneous rocks formed?
Cooled magma
How do Sedimentary rocks form?
When minerals and/or organic materials accumulate and become cemented together.
How do Metamorphic rocks form?
Increased pressure and/or temperature change the composition of the rock
What is the rock cycle?
A long, slow process that rocks take from deep in the Earth up to the surface
What are the three kinds of rocks?
Igneous, Sedimentary, and Metamorphic
What kind of Igneous rock forms below Earth's surface?
Intrusive
Between Clastic and Non-clastic, which is fragmented and which is crystalline?
Clastic rocks are fragmented, Non-Clastic rocks are crystalline
What kind of metamorphism occurs when increased pressure is introduced to the rock?
Regional Metamorphism
TRUE or FALSE: Igneous rocks can form directly from sedimentary rocks.
FALSE
What kind of scientist studies rocks?
A Geologist
What kind of Igneous rock forms above Earth's surface?
Extrusive
Are fossils found in clastic, organic, or chemical rocks?
Organic
What kind of metamorphism occurs when increased temperature is introduced to the rock?
Contact Metamorphism
TRUE or FALSE: Metamorphic rocks can melt into magma, which then cools into Igneous rock
TRUE
What layer of the Earth do we study rocks on?
The crust
What are the two texture types of Igneous rocks?
Coarse and fine grained
What are the two types of Non-Clastic rocks?
Organic and Chemical
What is foliation?
When the grains of rocks align and form bands around the rock.
TRUE or FALSE: Sediments can be formed by all three rock types if they face weathering and erosion
TRUE
How do categorize rocks?
Based on their composition and how they were formed
What are the two colorways of Igneous rocks?
Felsic and Mafic
A rock with over 2mm grain size and angular clasts is called....
Breccia
Which kind of metamorphism results in foliation?
Contact Metamorphism
What scientific law does the Rock Cycle follow?
Law of Conservation of Mass
