(Mon) City engineers don’t normally make buildings and

earthquake-proof and what do engineers do to make
these structures safer? (5 min / 4 pts)
Why:
It is too expensive to make a building
earthquake-proof
What do they do?
They reinforce the buildings, highways
and bridges to make them earthquakeresistant
(Tue) Earthquake/Rocks/Hazards Quiz – no warm up
(Wed) The Atlantic Mid-Ocean ridge is a special kind of

are 3 ways to tell that it is this kind of boundary?
(8 min / 8 pts)
(Wed) The Atlantic Mid-Ocean ridge is a special kind of
plate boundary. What type of boundary is it and what
are 3 ways to tell that it is this kind of boundary?
(8 min / 8 pts)
Type:
Divergent Plate Boundary
3 Ways to Tell:
Age of the Rocks – They get older the
farther away you get from the boundary
Magnetic Striping – Magnetic signature of
the rocks change in zebra striped patterns
Thickness of the Crust – Oceanic crust is
thinner near the boundary and thicker
farther away
(Thu) End of Geology Exam – no warm up
(Fri) Earthquakes make 3 main types of waves. What
are the names for these 3 types and what direction does
the earth move compared to the direction the wave
moves? (8 min / 12 pts)
(Fri) Earthquakes make 3 main types of waves. What
are the names for these 3 types and what direction does
the earth move compared to the direction the wave
moves? (8 min / 12 pts)
Types:
Primary, P or Longitudinal
Secondary, S or Transverse
Surface or Combination
Direction:
Earth moves same
direction as wave
motion
Earth moves
perpendicular or at right
angles to wave motion
Combination of same
and at right angles to
wave motion
