100
These are the three types of plate boundaries.
What are divergent, convergent, and transform?
100
This is the correct order of geologic eras, from youngest to oldest.
What is Cenozoic, Mesozoic, Paleozoic, Precambrian?
100
This is a synonym of intrusive igneous rocks.
What is plutonic?
100
These are the three main categories of sedimentary rocks.
What are clastic, biochemical/organic, and chemical?
100
This is the term for a layered metamorphic rock.
What is foliated?
200
These boundaries are characterized by shallow earthquakes and new crust being created.
What are divergent boundaries?
200
This law states that rocks wants to form in flat layers, so if there is deformation (folding, etc.), it must have happened after deposition.
What is the Law of Original Horizontality?
200
These are the two main types of composition for igneous rocks.
What are mafic and felsic?
200
Mudstone, sandstone, and breccia are all this kind of sedimentary rock.
What is a clastic sedimentary rock?
200
This rock is considered the highest grade metamorphic type.
What is gneiss?
300
These are 3 pieces of evidence in favor of Wegener's continental drift theory.
What are continent shapes, fossil/climate correlation, and common rock formations?
300
If you start with 8000 atoms of Carbon-14 (half life = 5730 years), how old would your sample be if there were 1000 atoms remaining?
What is 17,190 years old?
300
These volcanoes typically have a combination of ash and lava layers that make up it's conical shape.
What is a strato (composite) volcano?
300
Soil texture is primarily based on this.
What is grain size?
300
This mineral is distinguished by its pistachio green color and its appearance in many mafic and ultramafic rocks.
What is olivine?
400
Deep and shallow earthquakes, volcanism, and trenches are found along this kind of boundary (be very specific).
What is an ocean-continent convergent boundary?
400
This era accounts for ~80% of all of Earth's history.
What is the Precambrian?
400
This igneous texture is characterized by a fine-grained matrix with coarse-grained crystals sprinkled throughout the rock.
What is porphyritic?
400
These two sedimentary characteristics are the most important for naming a sed rock.
What are grain size and composition?
400
Biotite and muscovite are both often referred to as secondary name.
What is mica?
500
Determining the ages of seafloor basalts helped us determine this about plate tectonics.
What is how fast they're moving (i.e. rate = distance/time)?
500
This is the length of each half life if the amount of Radon-222 decays from 500g to 62.5g in 12 years?
What is 4 years?
500
You would expect to find lots of muscovite, potassium felspar, and quartz in this kind of intrusive igneous rock.
What is granite?
500
Limestone is typically formed from this.
What is calcium carbonate?
500
Low grade metamorphic rocks commonly have this particular category of minerals in them.
What are hydrous minerals?
