Answer 15

epeiric seas

Question 16

What geologic evidence for poleward temperature gradient of Permo-Carboniferous

glaciation (glacier formation

Question 17

what type of cyclic sedimentation of late Paleozoic

Answer 17

cyclothems

Question 18

what formed late Paleozoic

Answer 18

coal

Question 19

what was deposition on craton like during mississipi and pennsylvania

Answer 19

remarkably repetitive pattern

Question 20

what conditions needed to form coal

Answer 20

abundant vegetation preservation of organic matter

Question 21

where did coal mostly develop

Answer 21

lowland swamps

Question 22

why coal form in low land swamps of carboniferous

Answer 22

tree trunks leaf material abundant

Question 23

what provide ideal conditions for coal to form

Answer 23

coastal flood plains and swampy regions

Question 24

where do cyclothems happen

Answer 24

advancing delta fronts

Question 25

what is a delta

Answer 25

the separation of a major river into many smaller rivers and swamps as the river enters the sea

Question 26

what oxygen condition needed to form coal

Answer 26

anaerobic ( oxygen poor

Question 27

what 3 part cycle happened to make coal

Answer 27

deposition , colonization of plants , inundation (floods)

Question 28

what typical cyclothem sequence

Answer 28

marine sediment then non-marine then marine

Question 29

what causes cyclothem sequence

Answer 29

transgression -regression of water

Question 30

what happens during cyclothem sequence to make coal

Answer 30

sea level drops then swamps form then swamps flooded

Question 31

What were the cyclothem sequence like in late paleozoic

Answer 31

rapid oscillations (many events over short period

Question 32

possible cause of cyclothem

Answer 32

rise fall sea level

Question 33

what caused rise fall of paleozoic sea levels?

Answer 33

growth and shrinking of glaciers gondwana

Question 34

what tectonic event cause paleozoic change sea level

Answer 34

tectonic (plate ) up down whole continent

Question 35

what sea floor change lead to change sea level paleozoic

Answer 35

warping of sea floor

Question 36

why paleozoic clastic sediments to deltas have flucuated

Answer 36

changes in climate (rain fall) causing upland erosion and washing sediments to deltas
