Review for Exam
After the first draft was
published, a few more items were added in the topographic maps section.
On the exam,
you should be able to do the
Tsunamis, and Plate Tectonics
* Define earthquake.
* Tell how earthquakes are measured using seismographs.
illustrating the meaning of the terms epicenter and focus
(also called hypocenter) as they apply to
* Describe P-waves
their motion, velocity, arrival times,
and ability to travel through liquids.
* Explain why P- and S-waves reach seismometers at different times, and
tell how the time difference helps us learn how far away an earthquake
* Tell why it is necessary to have seismograms for an earthquake from
at least three different locations before we can locate an earthquake
* Examining seismograms from three monitoring stations, for each
monitoring station, calculate
the P-S time
difference, find the distance of the epicenter from the
station, and plot the distances on a map to locate the epicenter.
* Using the information from the seismographs and maps, plot the
position of a tsunami wave at various times as it moves outward from
* Using earthquake focus maps such as those produced by students in
analyze the patterns of earthquake epicenters that occur in various
terms of depth of
focus and pattern
of earthquakes, describe what would be expected in the following
environments: divergent boundaries, transform boundaries, convergent
boundaries with subduction, convergent boundaries with no subduction,
* Examine an earthquake focus map and form a reasonable hypothesis as
to the plate tectonic environment.
Visiting several sites on the NEIU campus, describe the use of geologic
materials in architecture and landscaping.
List the common elements that should appear on any map,
and explain how to use and/or interpret them.
* Explain how to use Earth's grid system (latitude and longitude),
including knowing the difference between north (+) and south (-)
latitude, east (+) and west (-) longitude, use of degrees, minutes, and
seconds, where zero latitude and zero longitude are, and what the
highest latitudes and longitudes are. (See p. 684-5 in your
the meaning and importance of the following:
contour interval contour
* Using a topographic map, locate higher and lower elevations.
* Interpret the spacing of contour lines and tell how it relates to
steepness of a slope.
* Interpret major features such as bodies of water, urban
buildings, roadways, and so on.
* Construct a "playdough" model of a landform, and then draw a map to
illustrate the landform.
* Using a map someone else has drawn, create a landform that fits what
the map illustrates.
Use contours to determine which direction a stream is flowing, even if the contours
are not labeled.
* Use latitude and longitude to locate a point on a topographic map;
starting with a point on a map, determine the latitude and longitude.
Complette a worksheet that asks you to examine several different
topographic maps and interpret different features on them.
