Review Sheet Test 2
These are suggested topics. Be sure to check your notes for any additional topics not
covered here. Instructor is not responsible for 100% inclusion of material on this review
sheet; however, it is likely that the test will cover fewer topics than are listed.
Use Geode Disk to study. You can use your code inside the cover of your text to go on
line for in depth quizzes. However, these quizzes cover more than is covered in class.
Use the power points and your notes.
You should bring a simple calculator (no cell phones) to calculate geothermal gradient.
Chapter 4:
Rev. questions Pg. 122 1,2,3,5,9,10,12, 13,14,15, 16, 17, 19, 20
Geothermal gradient Fig. 4.18; class handout and questions – how to
calculate gradient; 3 ways to melt rock: heat, decompression melting, presence of
volatiles such as
water . Bowens Reaction Series Fig. 4.23; Ways to vary
magma composition: crystal settling (also called magmatic differentiation), magma
mixing, melting of crust
Partial melting; pluton, magma, lava,
Chapter 5:
Volcanoes and other Igneous Activity: Especially note: Fig. 5.4, 5.6, 5.7,
5.14, 5.38, 5.39, 5.44; Rev. questions Pg. 162: 2, 3, 4, 8, 9, 10, 15, 18, 23, 24, 25, 26, 27
Terms include batholith, pluton, pillow lava, columnar joints, volcanic
neck, volcanic island arc, continental volcanic arc, crater, caldera., flood basalt, intraplate
volcanism,
hazards (lahar, lava, pyroclastic flow, ash, others?), shield,
stratovolcano, cinder cone or scoria cone
Volcano Maps Due: Plot the volcanoes discussed in class. Be sure
they are on the correct plate. Label with the name of the volcano.
For the test choose three volcanoes from these types: stratovolcano,
cinder cone, shield, caldera.
Be prepared to write about the location, names of plates, type of
boundary or hot spot, type of eruption expected, type of rock produced.
Be able to explain why there is a volcano in that location.
Chapter 6:
We did not cover soil types
Figures 6.1, 6.3, 6.4, 6.5, 6.14, 6.15, 6.16; Rev. questions 1,2,3,5,6,7
Terms pg. 190 including chemical weathering, mechanical weathering,
differential weathering, dissolution, hydrolysis, oxidation, frost wedging, biologic
activity, thermal
expansion, sheeting, spheroidal weathering, mass wasting,
dissolution of feldspars, Bowens reaction series and weathering patterns (fig. 6.16)
internal vs external process
weathering: mechanical, chemical
four contributors to mechanical weathering
three types of chemical weathering (oxidation hydrolysis and dissolution)
Dissolution of feldspar
effects of climate and surface area on chemical weathering
products of weathering: exfoliation domes, spheroidal, jointing, chemical
breakdown
Chapter 7
Note key terms pg. 219 including biochemical, cementation, types of
cement (silica, iron oxide, calcite), clastic or detrital texture, chemical sedimentary rock,
lithification
(burial, compaction, cementation, lithification), evaporite (halite,
gypsum), sorting; three general sedimentary environments (continental, transitional,
marine – an example
for each?) and questions 2,3,6,7,8,9,15,18.
Sedimentary rock formation Fig. 7.2 (steps in forming sedimentary
rocks), 7.4, 7.16,
Note: specific questions on rock types will be limited to conglomerate,
breccia, halite, limestone (in general) and sandstone.
Chapter 8
Note key terms Pg. 244 and questions 1-6, 11, 12, 17
Fig. 8.3, 8.4, 8.6, 8.20, 8.21, 8..22, 8.24, 8.26, 8.29
Agents of metamorphism
confining pressure vs differential stress – also can say “uniform stress” vs
“directional stress”
Role of hydrothermal fluids: transports ions to aid in recrystallization of
minerals
foliation, non-foliation, slaty rock cleavage formation
metamorphic environments: the plate boundary map with temperature and
pressures indicated.Figs. 8.3 and 8.29
index minerals: See fig. 8.25
