ess 101 || QUESTIONS WITH COMPLETE
SOLUTIONS!!
elastic strain correct answers a type of deformation in which the material returns to its
original shape when stress is relaxed
brittle strain correct answers rocks that break or fracture under stress
plastic strain correct answers permanent deformation of a solid with no failure by fracturing
reverse fault correct answers a type of fault where the hanging wall slides upward; caused by
compression in the crust
THE EARTHQUAKE HYPOCENTER correct answers a sudden rupture of intact rock or the
frictional slip of rock on a fault produces seismic waves. These waves move outward from
the point of rupture in all directions at once.
Lithification correct answers The process that converts sediments into solid rock by
compaction or cementation.
burial and compaction correct answers organisms are compacted into sediments to form rock
Cemetation correct answers The process by which dissolved minerals crystallize and glue
particles of sediment together into one mass.
clastic sedimentary rocks correct answers accumulated particles of broken rock or skeletal
remains of dead organisms.
conglomerate correct answers
sandstone correct answers A sedimentary rock formed by cementing grains of sand over time.
Siltstone correct answers fine-grained sedimentary rock generally composed of very small
quartz grains
Mudstone correct answers Very fine-grained sedimentary rock that will not easily split into
sheets.
sedimentary breccia correct answers A coarse-grained sedimentary rock (grains coarser than
2 mm) formed by the cementation of angular rubble.
Coquina correct answers a soft porous limestone composed of shell and coral
chemical sedimentary rocks correct answers rocks formed from minerals precipitated from a
solution or left behind by evaporation
limestone correct answers a sedimentary rock consisting mainly of calcium that was
deposited by the remains of marine animals
