  First, if you have a question, it is much better to put it in as a separate post in <Post a New Question> rather than attaching it to a previous question, where is more likely to be overlooked.
  
  Since this is not my area of expertise, I searched Google under the key words "Plants rock weathering" to get these possible sources:
  
  http://www.globalchange.umich.edu/globalchange1/current/lectures/soils/soils.html
  http://www.treesearch.fs.fed.us/pubs/24794

  There are more, if you want to continue the search. In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.
  
  I hope this helps. Thanks for asking.

Mitosis involves normal body maintanence and growth, while meiosis deals with reproduction. If meiosis did not occur, the number of chromosomes would double with each generation.

I hope this helps. Thanks for asking.
