#1
Front (Question)

weathering

Back (Answer)

pre existing rocks break down mechanically or chemically to produce sediment

#2
Front (Question)

clastic rocks

Back (Answer)

formed from mechanical weathering

#3
Front (Question)

mechanical weathering

Back (Answer)

when a material is broken into smaller pieces which still retain characteristics of the original material

#4
Front (Question)

lithification

Back (Answer)

sediment turns into solid rock via compaction and cementation

#5
Front (Question)

chemical weathering

Back (Answer)

material is altered by chemical action resulting in new material

#6
Front (Question)

deposition

Back (Answer)

sediment deposited in lakes, rivers, and oceans, or accumulates in desserts

#7
Front (Question)

erosion

Back (Answer)

erosional agents (wind, rain, ice) transport the sediment to new locations

#8
Front (Question)

biochemical

Back (Answer)

accumulation of living material

#9
Front (Question)

chemical rocks

Back (Answer)

formed from chemical weathering

#10
Front (Question)

shale (clastic)

Back (Answer)

fine particles compacted to form thin layers

#11
Front (Question)

breccia (clastic)

Back (Answer)

poorly sorted angular particles

#12
Front (Question)

sandstone (clastic)

Back (Answer)

well sorted sand size particles

#13
Front (Question)

conglomerate (clastic)

Back (Answer)

poorly sorted round particles

#14
Front (Question)

what can we tell from grain size?

Back (Answer)

• grain size decreases with decreasing current velocity • larger grain sizes are closer to the source of weathering

#15
Front (Question)

limestone (CS) forms by

Back (Answer)

chemical precipitation in shallow water

#16
Front (Question)

rock salt forms (CS) by

Back (Answer)

evaporation of shallow seas and lagoons

#17
Front (Question)

High velocity gives us what texture?

Back (Answer)

coarse

#18
Front (Question)

low velocity gives us what texture?

Back (Answer)

fine

#19
Front (Question)

Evaporites (CS)

Back (Answer)

result of evaporation of water

#20
Front (Question)

precipitates (CS)

Back (Answer)

changes in environmental conditions

Back (Answer)

a precipitate

#23

sylvite precipitates are?

Back (Answer)

evaporites

#24
