Rock Cycle I
Can a mineral of the same composition have multiple colors?
Yes
Name the three classifications of rocks
Sedimentary, igneous, metamorphic
Name the three types of plate boundaries
convergent, divergent, and transform
What are two types of glaciers?
Alpine and Continental
True or false, faults are longer than the rocks they cut through?
True
What is the difference between cleavage and fracture?
Cleavage: property where a mineral break alone smooth planes
Fracture: property where a mineral breaks in a random pattern
Name the parent rock of slate
Shale
What is the epicenter of an earthquake always directly above?
focus
What is the main driving force for glacial flow?
Gravity
What is a real world application of radiometric dating?
What does the color of Arkose tell you about the rock?
pink - high in potassium feldspar
What type of grain shape to conglomerates exhibit?
Rounded grains
Which waves travel the slowest?
S-waves
Which of the following has the highest porosity and the highest permeability?
Silt
Gravel
Sand
Permeability: Gravel
Porosity: Silt
What is the difference between relative and radiometric dating?
radiometric: use of radio isotopes to determine exact age
relative: uses order of rock layers to determine relative age
Would the crystal size on an igneous rock be larger or smaller if the rock cooled quickly?
What is the most common igneous rock in the continental crust?
Granite
The Andes are an example of what plate boundary?
Oceanic-continental convergence
Define Porosity
Porosity is a property of a solid material and is the ratio of pore space and total volume of a sample.
Name the three types of unconformities
Angular unconformity
nonconformity
disconformity
Describe an area where metamorphism occurs.
Subduction zone
What is the one sedimentary rock that is generally responsible for karst formation?
Limestone
Where is oceanic crust created? Where is it destroyed?
Created: mid-ocean ridges
Destroyed: Subduction zones
Permeability depends on...
1. Size of pores
2. porosity
3. connectedness of the pores
What is a half-life?
The amount of time for half of the atoms in the nucleus of a radioactive nuclide to decay.
