Shake, Rattle, And Roll
100
Molten rock with added volatiles is given this name.
What is magma?
100
This states that newer rock layers are formed on top of older rock layers
What is the Principle of Superposition?
100
The process by which metamorphic rocks are created.
What is metamorphosis?
100
The type of weathering observed when water dissolves a rock.
What is chemical weathering?
100
The location along a fault where an earthquake is generated.
What is the focus?
200
Lava rich in this element increases its viscosity.
What is silicon (Si)?
200
The percent of parent atoms remaining after they have underwent 2 half lives.
What is 25%?
200
Temperature increases as depth increases is defined by this process.
What is geothermal gradient?
200
The process of weathering produces these building blocks of sedimentary rocks.
What are sediments?
200
These are fractures along Earth's crust.
What are faults?
300
Igneous rocks are given the descriptor 'mafic' if they are rich in these elements.
What are magnesium and iron?
300
This unconformity occurs between two sedimentary layers with a drastic difference in time between them.
What is a disconformity?
300
These are the three agents of the metamorphic process.
What is pressure, time, and fluids?
300
The process by which sedimentary rocks are formed.
What is lithification?
300
The fault exhibited when the hanging wall slides down the foot wall.
What is a normal fault?
400
These volcanoes are relatively low profile and are produced from silica-poor lava flows.
What are shield volcanoes?
400
Parent atoms decay into these.
What are daughter atoms?
400
The pressure that is exhibited by a rock due to its depth.
What is confined pressure?
400
This second step in the formation of sedimentary rocks "glues" sediments together.
What is cementation?
400
This scale is the most scientific way of measuring an earthquake.
What is the moment-magnitude scale?
500
Escaping gas from cooling lava give igneous rocks this texture.
What is vesicular?
500
Isotopes are elements with the same atomic number but differing atomic mass because they have different amount of these atomic particles.
What are neutrons?
500
Pressure produces this texture as depicted by bands of minerals that have been aligned.
What is foliation?
500
Coal and Chert are two examples of this kind of sedimentary rock.
What are chemical/biogenic rocks?
500
The time difference between the S and P wave can be used to measure what?
What is distance from the epicenter?
