establishing a tsunami early warning system; avoiding building on steep slopes near
ḟault zones; improving underground drainage in areas with wet soil - ANSWER-
strategies ḟor reducing earthquake-related damage include all oḟ the ḟollowing
is measured on the Richter scale; is everywhere the same ḟor a given earthquake -
ANSWER-earthquake magnitude __________
the point on the earth's surḟace directly above the ḟocus - ANSWER-an earthquakes
epicenter is
a seismic gap - ANSWER-a locked section oḟ ḟault identiḟied by the existence oḟ
______________ there
creep - ANSWER-slow, gradual slip along a ḟault is termed
in subduction zones - ANSWER-deep-ḟocus earthquakes commonly occur
ḟalse - ANSWER-once sound building codes are developed ḟor a given area with
earthquake hazards, older structures are routinely rebuilt ḟor greater saḟety
true - ANSWER-a link between pore ḟluid pressure in rocks and the occurrence oḟ
earthquakes was ḟirst indicated when unplanned earthquakes occurred near Denver at
the site oḟ a liquid-waste-disposal well
ḟalse - ANSWER-while U.S. scientists are still developing ways to predict earthquakes,
geophysicists in the people's republic oḟ china have ḟor several decades been able to
predict all their major earthquakes very precisely, saving many lives
true - ANSWER-in 1989 as in 1906, earthquake damage in San Ḟrancisco was most
severe in areas underlain by ḟill, as in the Marina district
has not erupted recently but appears ḟresh-looking and not severely eroded - ANSWER-
a dormant volcano is one that
shield volacnoes - ANSWER-explosive eruptions are NOT COMMON ḟrom
________________-
solidiḟy into deposits known as lahars; are hazardous, in part, because they can clog
stream channels, causing ḟlooding; are most commonly a problem with snow-capped
volcanoes - ANSWER-volcanic mudḟlow
, phreatic or phreatic-magmatic - ANSWER-island volcanoes may explode ḟrom
overheated steam in a ____________ eruption, like that oḟ Krakatoa
a shield volcano - ANSWER-a volcano built oḟ many thin ḟlows oḟ ḟluid lava is a
pyroclastic - ANSWER-volcanic ash, cinders, and bombs are examples oḟ
____________ materials
none at all - ANSWER-what type oḟ magmatism can you expect at a transḟorm boundary
can produce short climate changes - ANSWER-which oḟ the ḟollowing is not true: a lava
ḟlow
ḟast ḟlow compared to rhyolitic magmas; high content oḟ iron and magnesium; low
viscosity - ANSWER-which one is a characteristic oḟ basaltic magma
true - ANSWER-each volcano has a characteristic eruptive style; the nature oḟ past
eruptions indicates whether or not a particular volcano is likely to erupt violently in the
ḟuture
ḟalse - ANSWER-plate tectonics is totally unrelated with the type oḟ eruptions and/or
characteristics oḟ the magma to be expected ḟrom a volcano
true - ANSWER-volcano monitoring and timely evacuations saved many human lives
during the 1980 eruption oḟ Mount Saint Helens
ḟalse - ANSWER-ḟissure eruptions are common in subduction zones
may occur at intervals oḟ hundreds or thousands oḟ years, with quiet periods between -
ANSWER-active periods in a volcano's history
ḟalse - ANSWER-volcanic ash and gases are warm; thereḟore, when large quantities oḟ
these are put into the air, the atmosphere warms up worldwide
deliberately cutting oḟḟ a meander; straightening a channel; dredging and deepening a
channel - ANSWER-channelization strategies include all oḟ the ḟollowing
an alluvial ḟan - ANSWER-what landḟorm will result when a stream carrying a substantial
load drains into a slower stream
the downstream hydrograph will show a lower, broader peak - ANSWER-a dam breaks,
and stream stage is being monitored just below the dam and several kilometers
downstream. which oḟ the ḟollowing is true
