What is the fractional scale on this quad? - ANSWER-1:24,000
Judging from the fractional scale, what size quad do you suppose Menan Buttes
Quadrangle is? - ANSWER-7 1/2-minute
There's a benchmark (BM) marked with elevation 4826 feet along the Union
Pacific Railroad. What is the distance, to the nearest tenth of a mile, between the
BM and the X marking the approximate center of South Menan Butte? -
ANSWER-1.4 miles
What is the latitude at (A) the north pole? (B) The south pole? - ANSWER-90*N
and 90*S
What do you imagine is the maximum longitude value on earth? - ANSWER-180*
(180*W or 180*E. They are equal)
How far- to the nearest tenth of a kilometer- is the well in section 11 from the
southwest corner of section 10? - ANSWER-1.8 kilometers
The southwest corner of section 10 is approximately what direction- expressed as a
bearing- from the x that marks the approximate center on North Menan Butte? -
ANSWER-S 30* W
See the stippled areas in section 23, southeast of South Menan Butte. What does
this stipple designate? - ANSWER-Sand or mud area, dunes or shifting sand.
, What can you say about the elevation in feet of the higher of the two hills in Figure
1.19? - ANSWER-The higher hill is more than 20 feet high, but less than 25 feet
high
How about the lower hill? - ANSWER-The higher hill is more than 15 feet high,
but less than 20 feet high
What is the contour interval on the Menan Buttes topographic quadrangle? -
ANSWER-100 feet
Determine the distance to an earthquake at a station that recieves P and S waves
5.0 minutes apart. - ANSWER-NOT approximately 1,400 kilometers
NOT approximately 2,800 kilometers
At this point, from the information in figure 8.6A, how specific can you be as
concerns the location of that earthquake? - ANSWER-The earthquake is
somewhere on the circle around Seattle.
At the crest of south Menan Butte there are contour lines with tick-marks. (A) what
do these tick-marks indicate? - ANSWER-Depression (me lol)
What is the approximate height, or the approximate depth, of the feature bounded
by these tick-marks on south Menan Butte? - ANSWER-Between 107 and 117 feet
Again, with reference to south Menan Butte. In the elevation range of 4900-5100
feet, where is the slope steeper - on the northeast side of the Butte or on the
southwest side of the Butte? - ANSWER-On the southwest side of the butte
Given the origin of cinder cones, describe in this chapter, what do you suppose
accounts for the asymmetry of south Menan Butte? - ANSWER-Wind out of the
southwest blew cinders and ash towards the northeast, creating a larger and more
gently sloping accumulation on the northeast side of the butte.
Judging from the seismogram in figure 8.4, which wave appears to be the most
damaging? - ANSWER-Surface waves.
