The Attempt at a Solution


No, it does not mean it is correct. this is because...?

First, 'homogeneous' in general parlance does not mean 'correct'. It means 'of uniform consistency'. As in 'homogenized milk' or 'homogeneous societies'.

Second, 'homogeneous' referring to differential equations has very distinct meanings. In fact, there are 2 meanings attached to the term if the d.e. is 1st order, which is nice and confusing, and one for linear d.e.'s of any order.

It's a dumb term. Makes absolutely no sense. But you have to learn to handle d.e.'s in the form described as "homogeneous" anyway.
 
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.
