Geology 105 Final Beutel QUESTIONS
AND ANSWERS
1. Carbon isotopes - ANSWER-Carbon Dating. Radiocarbon, or carbon 14, is an
isotope of the element carbon this is unstable and weakly radioactive. ... It should
be cited though that radiocarbon courting results suggest whilst the organism
become alive however no longer while a cloth from that organism changed into
used.
2. Carboniferous CO2 - ANSWER-During the Carboniferous period, when maximum of
the coal and oil deposits have been formed, about 1014 heaps of carbon dioxide
were withdrawn from the surroundings-ocean device. This dazzling loss ought to
have dropped the earth's temperature to cold stages indeed
3. Changing Climates - ANSWER-Evidence inside the rock document, fossil record
evidence, oxygen isotopes, orbital cycles (seasons through milankovich)
4. Climate at some point of the Mesozoic - ANSWER-The weather become warmer, the
seasons had been very slight, the sea degree was higher, and there was no polar
ice. ... The Mesozoic Era lasted approximately one hundred eighty million years,
and is split into 3 durations, the Triassic, the Jurassic, and the Cretaceous.
5. CO2 and vegetation - ANSWER-Plants soak up CO2 for photosynthesis.
6. Cold phases - ANSWER-"glacial durations" ice ages. 2 important Precambrian ice a
while= snowball earths.
7. Convergent Boundaries - ANSWER-oceanic-continental, new crust created, Mt.S
and volcanoes created
8. Dating strategies - ANSWER-Radiometric: determine& daughter isotopes.
9. Dinosaurs heat or cold blooded? - ANSWER-Metabolic alternatives. The principal
opportunities are that: Dinosaurs were bloodless-blooded, like cutting-edge
reptiles, except that the massive length of many would have stabilized their frame
temperatures. They have been warm-blooded, greater like modern-day mammals
or birds than current reptiles.
10.Divergent Boundaries - ANSWER-creates ridges and valleys, seafloor spreading
11.East Coast Orogenies - ANSWER-Taconic Orogeny ~440 mya Island arc hits
(Ordivician) Accadian Orogeny ~380 mya - Continental bit hits
Alleghanian/Appalachian Orogeny ~three hundred mya - Africa hits.
12.Event happening on pinnacle of this gradual extinction- - ANSWER-Siberian Trap flood
basalts, inflicting reefs to die out. How do the Siberian traps modify weather?
-Puts huge amounts of CO2 in environment, additionally ash clouds block sun.
Climate instability.
13.How do they modify the chemistry of the oceans/rain?- Build-up of CO2 in deep water
Acidic oceans
14.Evidence for extinction of dinosaurs. - ANSWER-Shocked quartz unfold out over the
globe
, 15.proof that birds are genuinely dinosaur decendent - ANSWER-Similar hip structure-
lizard hipped,What line of dinosaurs do they come from? -fowl -hipped dinosaurs,
Ornithischian.Feathers
Bird Feet
Nesting conduct
Similar Arm Structure
Air Sacks
Light Hollow Bones
Large Brain
16.Evolution - ANSWER-driven via herbal selection; species generating maximum
offspring will live to tell the tale, i.E best adapted
17.Evolution - ANSWER-the alternate within the characteristics of a species over
numerous generations and relies at the method of natural selection. The concept
of evolution is based on the idea that all species? Are related and gradually
exchange over the years.
18.Formation of oceans - ANSWER-waters reacted with carbon dioxide from
surroundings to deposit calcium and magnesium carbonates as limestone.
Weathering of rocks on the primary continents leached salts into the waters.
Stromatolites shaped by using cyanobacteria imply fully saline oceans existed
around 3.Five BYA.
19.Formation of the environment - ANSWER-consisted of mild gases hydrogen and
helium, volcanic pastime caused risky gases. Amount of oxygen in atmosphere
slowly inc. As microorganisms converted carbon dioxide into oxygen through
photosynthesis, Clouds of water vapor condensed and brought about forming
floor water and finally oceans.
20.Formation of the Earth - ANSWER-the rocks and ice that shared the identical orbit
around the developing Sun the most important our bodies in each ring attracted
the maximum cloth and formed planetesimals. As those grew larger their
gravitational pull fashioned a sphere shape, producing excessive power effect
heating& melting. The first 500 MY earths middle and mantle consisted of molten
iron and convections...
21.Geologic time scale - ANSWER-
22.How CO2 varies and pertains to climate and the way CO2 stages are changed (with the
aid of both existence and tectonics) - ANSWER-carbon dioxide controls temperature
due to the fact the carbon dioxide molecules inside the air soak up infrared
radiation. The carbon dioxide and other gases within the ecosystem are certainly
obvious to the seen radiation that provides the solar's power to the earth. But the
earth in flip reradiates much of the energy in the invisible infrared location of the
spectrum.
23.How do massive brains affect what we devour? - ANSWER-Large brains purpose
extra numerous diets to supplement the energy wished
24.How do we recognize if there was an extinction, mt. Constructing occasion, volcanoes,
ect. ?? - ANSWER-The fossil file, examining sediment layers and styles, Carbon
