Im bit confused about what is exactly the difference between the terms, which process every term describes ?

aggregation: two or more stick together
nucleation: a start from 'zero'
growth: from non-zero to a little more

We are talking crystals here, I hope ? (i.e. nothing biological :wink: )

Thank you so much for the answer :) , yes I'm talking about crystals and nothing biological :D
Then the coalescence which process it describes?
 
A further question ! My answer: don't really know. Didn't encounter it so far. Googled 'crystal coalescence and aggregation' and get the impression coalescence is softer (either it happens in the liquid phase, or comes down to a near perfect match in the early solid phase -- but I speculate)
