Any ideas on how to start? Is, the distributed moment constant along the beam?

yes ,, its uniformally distributed.
 
Since the moment is uniform and continuous (also the weight distribution is considered uniform so the reaction forces at the supports are equal to each other), it does not vary with distance. How is the bending moment related to the shear force?

right so it going to to straight line >>>>

ok . ...
is there any answer else?
 
Again, how is the bending moment related to the shear? You should have covered this. It's a first order differential equation that can be solved by straightforward integration.
 
To solve this, I first used the units to work out that a= m* a/m, i.e. t=z/λ. This would allow you to determine the time duration within an interval section by section and then add this to the previous ones to obtain the age of the respective layer. However, this would require a constant thickness per year for each interval. However, since this is most likely not the case, my next consideration was that the age must be the integral of a 1/λ(z) function, which I cannot model.
