unit 2-3a
unconformity
an irregular surface separating 2 series of rocks
sediments were laid down by the flood from different areas and cut through by floodwaters
what is the biblical perspective on unconformities and how they came to be
deep and wide erosion
marine animals far above sea level and throughout continents
sand carried across continents
what are the factors for biblical perspective on unconformities
C-14 dating
organic material uses what kind of dating
radiometric dating
what is a clock based on radioactive decay
half life
what is the particular rate of decay for radioactive decay
assume a constant rate of decay (most important)
assume nothing comes into or leaves the system
assume no daughter element present at beginning
what are the main assumptions of radiometric dating
perimineralization
the process by which the organic tissues of an organism are replaced by mineral deposits
one type of organism rapidly decreases to be replaced by another
what is the evolutionary view of extinctions
indicates a change in location as the floodwaters prevailed
what is the biblical view on extinctions
periods
the times between extinctions
billions of years
eon
hundreds of millions of years
era
tens of millions of years
period
millions of years
epoch
thousands of years
age
hadeon era
what was the eon where earth was presumed to be hellish
indicates the life found in specific regions of the pre flood world
what is the biblical view on periods
eon
era
period
epoch
age
label the eons, epochs ect by the longest to shortest
cambrian explosion
where all the marine fossils show up
eco-sedimentary zones
way of thinking of the fossil record; organisms buried where they live
precambrian time (spans billions of years)
which time of the earth was mostly vacant rock with occasional microscopic bacteria
precambrian
which evolutionary time period was the rocks deposited before the flood correlation
paleozoic era
which era had the cambrian explosion
paleozoic era
creatures buried early in the flood (marine ecosystems and coastal) correlates to this evolutionary time era
mesozoic era
which evolutionary time period had dinosaurs and small mammals
mesozoic era
this evolutionary era correlates to creatures buried when the flood started terrestrial ecosystems
coelacanth
what fish was for years used as proof as a transitional form but turned out to be alive
asteroid impact
what is the secular way of explaining the extinction of the dinosaurs
cenozoic era
which era do you find large mammals and birds
cenozoic era
what era correlates with the final stages of earth being covered in water and recessional phase of flood
cenozoic era
what era is associated with tectonic disturbance
humans have gradually gotten more advanced in their growth
what is the evolutionary perspective on human history
shows the growth of civilization since the flood
what is the biblical perspective on human history
atmosphere
what is the envelope of gases around the earth
hydrosphere
the total amount of water on the earth
nitrogen (78%)
what is the 1st most abundant gas in the atmosphere
oxygen (21%)
what is the 2nd most abundant gas in the atmosphere
nitrogen
oxygen
argon
carbon dioxide
what are the 4 most abundant gases in the atmosphere
thermosphere
in which atmosphere are there single oxygen atoms that are very reactive
troposphere
what is the layer that extends up to 7 miles above the surface of the earth
troposphere
in which region of the atmosphere do the temps decrease to -55 C
troposphere
what region of the atmosphere contains all the earths weather
stratosphere
which region of the atmosphere extends from 11-50km above the surface of the earth
stratosphere
which region of the atmosphere causes a temp rise to 10 C
UVC
which type of UV light is entirely absorbed in the ozone layer
mesosphere
what is the middle layer/region of the atmosphere
mesosphere
which region of the atmosphere extends from 50-80 km above the surface of the earth
mesosphere
which region of the atmosphere has the temp decrease to -75 C
stratosphere
in this zone the higher you go the hotter it gets
mesosphere
in this region of the atmosphere the temps decrease the higher you go
mesosphere
what is the coldest portion of th atmosphere
mesosphere
which region of the atmosphere do meteors burn up in
thermosphere
which region of the atmosphere extends from 80-600km above the surface of the earth
karmen line
how has space been traditionally defined at abt 100 km above the earth
thermosphere
what region of the atmosphere contains the ionosphere
thermosphere
which region of the atmosphere has temperature increasing to 2000 C
ionosphere
which region of the atmosphere absorbs high energy radiation from the sun
ionosphere
which layer of the atmosphere produces auroras
ionosphere
what is the special layer of oxygen atoms that get bombarded with the highest form of UV from the sun
compression and air resistance
why do meteors burn up in the mesosphere
thermosphere
which of the region sof the atmosphere is associated with temperature
