EAS FINAL EXAM 3 REVIEW QUESTIONS
Why do you think earthquakes are rare at depths greater than a few kilometers below
Earth's surface?
(a) Because there is magma everywhere at depth preventing earthquakes,
(b) Because earthquakes can only be generated in the mantle,
(c) Because water is required to generate earthquakes,
(d) Because mountains need to be present for earthquakes to occur,
(e) Because rocks become ductile at higher temperature and confining pressure at
depth - Answers :Because rocks become ductile at higher temperature and confining
pressure at depth
The actual source of an earthquake, located somewhere
at depth, is called the
(a) focus,
(b) epicenter,
(c) magnitude,
(d) intensity,
(e) None of the above - Answers :focus,
Which of the following is used to make long-term
earthquake predictions?
(a) the presence of radon gas near faults
(b) unusual behavior of animals
(c) changes in water levels in wells
D recurrence intervals of earthquakes along the fault
(e) the area and length of the fault and the rigidity of the rocks - Answers :recurrence
intervals of earthquakes along the fault
Earthquake early warning systems rely on what?
(a) Detection and analysis of the P-wave,
(b) A long record of earthquake recurrence along the fault,
(c) An analysis of seismic gaps,
(d) An analysis of locked and creeping segments of a fault,
(e) Detection of some anomaly near the fault due to cracking before the main slip -
Answers :Detection and analysis of the P-wave,
The particle in an atom that carries the positive charge is the
(a) cation,
(b) anion,
(c) proton,
(d) neutron,
(e)electron - Answers :proton
Which of the following chemical bonds is the weakest
, (other things being equal)?
(a) covalent bonds
(b) ionic bond
(c) metallic bond
(d) van der Waals bond
(e) not necessarily any of the above - Answers :van der Waals bond
15. Which of the following minerals is used directly in
the manufacture of glass?
(a) gypsum
(b) mica
(c) feldspar
(d) clay
(e) diamond - Answers :feldspar
The two properties that are essential for something to be called a mineral are
(a) solid and naturally occurring,
(b) inorganic and naturally occurring,
(c) fixed chemical composition and
solid,
(d) definite physical properties and naturally
occurring,
(e) crystalline and naturally occurring. - Answers :crystalline and naturally occurring.
Which of the following is true of any element?
(a) it needs to bond with a similar element
(b) it wants to achieve a complete outer electron shell
(c) it wants to obtain more electrons
(d) its electrons want to jump to a higher energy level and absorb light
(e) it wants to form a crystalline structure - Answers :it wants to achieve a complete
outer electron shell
18. Looking at the "dot diagram" below (the dots represent the number of electrons in
the outer shell of the (neutral atom), what charge do you expect F (fluorine) to have as
an ion? (a) +1,
(b) +2,
(c) -1,
(d) -2,
(e) no charge; it will prefer to remain as is. - Answers :-1
The series of figures below shows a map view of a fault (line) with eight markers
(circles) that were placed in the year 2000 (leftmost figure). The next three figures show
the points as they were surveyed over the next 12 years. This fault has not produced an
earthquake in a long time. Should the people living near this fault be concerned?
(a) Yes, because the fault is active and appears to be locked,
Why do you think earthquakes are rare at depths greater than a few kilometers below
