1.Using the Visual Overview on pages 224-225 and your amassed knowledge: a. summarizes how the burial of organic carbon (C), alteration of carbonates at high temps, and changes in rates of weathering alter greenhouse warming by Earth’s atmosphere, and b. explain how C isotopes are used to assess rates of burial of organic C. in Earth System History Less carbon returns to the atmosphere as CO. CO, TIONS OF More burial and less decay removes less oxygen from CO, AND o o, o, the RATE OF BURIAL OF ORGANIC CARBON CYCLING OF OXII CARBON THROUGH MARINE CARBONATES platform MacBook AirExplanation / Answer
a carbon is removed into long term storage by burial of sedimentary strata especially coal and black shale that store organic biomass.
when these carbon enters atmosphere they absorb the sun long wave radiation which reflected by earth and heats the atmosphere resulting in the occurence of global warming.
b an isotopic signature is the ratio of non radiogenic stable isotopes,stable radiogenic isotopes of particular elements in an investigated material. The ratio of isotopes in asample material are measured by isotope ratio mass spectrometry,this process is called ISOTYPE ANALYSIS
the ratio of C 13/ C 12 of burial carbon assesment rates can be analysed.
