Igneous rocks are formed from the cooling of what two liquid-like materials?
What are magma and lava?
100
These are the two things that rocks are subjected to in order to be metamorphosed.
What are heat and pressure?
100
Sedimentary rocks are generally made up of small pieces of what?
What is older rock?
100
The Earth is this many years old.
What is 4.6 billion?
100
These are the two main types of waves that earthquakes create.
What are P and S waves?
200
These are two differences between mafic and felsic rocks.
What are color, density, or chemical composition?
200
These metamorphic rocks contain large amounts of mica, giving it a shiny, glittery look. Many also contain garnets.
What is schist?
200
This type of rock is formed from the products of physical weathering, for example conglomerate rocks.
What is a clastic sedimentary rock?
200
This layer of the Earth contains the crust and part of the mantle.
What is the lithosphere?
200
This is the general speed of a P-Wave.
What is 6km/s
300
This is the name I would give an intrusive, intermediate igneous rock.
What is diorite?
300
This is the name of metamorphism that occurs at a subduction zone, over large areas.
What is regional metamorphism?
300
These sedimentary rocks are made up of compounds that precipitate out of a solution.
What are chemical sedimentary rocks?
300
This is the name of the theory that explains the creation of the universe. It also has a humorous pop culture affiliation!
What is the big bang theory?
300
This is the process by which you use seismic data from three different stations to locate the epicenter of an earthquake.
What is triangulation?
400
These are the two main mafic igneous rocks that we studied in lab.
What are gabbro and basalt?
400
This is the rock name I would give to a metamorphosed rock that contained calcium carbonate.
What is marble?
400
Deposited by wind or water, sandstones sometimes display these angled layers.
What is crossbedding?
400
This is the study of the internal magnetic orientation of rocks and helps us understand the location of continents millions of years ago.
What is paleomagnetism.
400
This is an example of the depth of an earthquake that geologists consider "deep".
What is 300-700km?
500
These are the three different ways that rock can be melted to form a magma.
What are increased heat, decompression, or addition of impurities?
500
Slate and phyllite both display this kind of metamorphic rock texture.
What is slaty cleavage?
500
When they're big geologists call them beds, but when they're small geologists call these layers what?
What is a lamination?
500
This is the charge of a cation.
What is positive?
500
These are the two types plate boundaries along which you may expect to experience earthquakes.
What are transform boundaries and convergent boundaries?
