SOE 101 QUIZ 2 QUESTIONS VERIFIED ANSWERS
What is differentiation? - answers - process of separating out the constituents of a
planetary body as a consequence of their density, resulting in distinct layers
When did differentiation happen on earth? - answers - 4.49 ga ago, lasted 100 ma
What are the layers of the earth? (in order, bottom to top) - answers - inner core, outer
core, lower mantle, upper mantle, crust
What layer of the earth is the least dense? - answers - crust
What is density? - answers - the quantity of mass per unit volume
What is the equation for density? - answers - mass/volume
Is oceanic or continental crust denser? - answers - oceanic
What is earth made of? - answers - iron, oxygen, silicon
What is the most common element the earth is made of? - answers - iron
What is the most densest element the earth is made of? - answers - iron
Where does the less dense material go? - answers - the atmosphere
What are the two main types of seismic waves? - answers - body waves and surface
waves
What are the two types of body waves? - answers - p (primary) waves and s
(secondary) waves
P waves and s waves - answers - p waves go through solid and liquid materials but are
refracted
S waves go through only solid material
Where do surface waves travel? - answers - through the crust - do the most damage in
earthquakes
How do you determine the size of the inner and outer core? - answers - use s wave (the
size of the shadow zone)
Where do earthquake occur? - answers - the focus
