1) the eventual fate of most carbon in the weathering process is the deep ocean. what processes occur to transfer carbon to the deep ocean? consider organic and inorganic pathways.
( i know it is something like - physical and biological processes)
2) the figure below shows a depiction of the organic carbon cycle including the main reservoirs (gtc) and fluxes (gtc/year).
(a) estimate the residence time of carbon in the atmosphere.
(b) estimate the residence time of carbon in sedimentary rocks.
(c) which of the fluxes depicted in the diagram is enhanced though the burning of fossil fuels as part of human activities?
13) answer the following question in one or a few sentences.
• why does life on earth need to recycle carbon on short timescales?
• in the organic carbon cycle, what organisms are the most critical participants, and why?
•describe and draw the functioning of the upper ocean organic carbon cycle? be sure to label the two primary processes.
16) explain the basic idea of a parametrization used in global circulation models. what is it and why is it required?
