cofc geology 105 lab final- seperated
QUESTIONS AND ANSWERS
1. Analogous structures - ANSWER-similarities among unrelated species that result
from convergent evolution
2. angular disconformity - ANSWER-horizontal layers of sedimentary rock; frequently
tilted and uplifted
3. asymmetrical ripple marks - ANSWER-- shaped by one-directional currents
4. biological evolution - ANSWER-change within the heritable traits of biological
populations through the years.
5. Chalk - ANSWER-sediment: natural cloth
depositional surroundings: deep ocean
6. Characteristics of lobe-finned fish - ANSWER-- fins are bendy; have several big
bones with smaller bones alongside the brink
- fins are probably useful for supporting them on land
- early ancestor of amphibians
7. Characteristics of ray-finned fish - ANSWER-plenty of long thin bones in a fan shape
8. coal - ANSWER-sediment: carbon
depositional environment: marsh/swamp
9. coarsening-upward - ANSWER-regression; power to deposit heavier/coarser grains
ought to be better than electricity to deposit finer grains (grain length is growing
upward)
10.coastal environment impacts of sea level upward push - ANSWER-erosion of beaches,
flooding of marshes/wetlands, growth salinity damaging plant/animal ecosystems
11.concurrent variety - ANSWER-"overlap" of geologic range of fossils located in
rock/sediment layer
12.conglomerate - ANSWER-sediment: unsorted
depositional surroundings: alluvial fan/river
13.Convergent Evolution - ANSWER-Process by which unrelated organisms
independently evolve similarities while adapting to comparable environments
(saber-toothed predators had big canines though unrelated)
14.coquina - ANSWER-- sedimentary rock crafted from fossilized seashells stuck
together
- high energy
- shallow ocean
15.pass-bedded sandstone - ANSWER-sedimentary structure: crossbeds
sediment: sand
depositional surroundings: wilderness/coast
16.cross-bedding - ANSWER-bureaucracy as willing layers of sediment are carried
forward across a horizontal floor
depositional environment: barren region/beach
