Tree rings form because in winter, the cambrium (xylem, phloem etc) grows very slowly, with small cells, and in spring/simmer it grows rapidly with larger cells. As the tree grows, these differences are shown as bands in the wood. We can tell the conditions the tree was in during a year from the thickness and features of these rings

hmm....the answer is: A LOT
well, maybe you can make a search on those. (we have topics related to photosynthesis and cellular respiration too.)

or you can have a look at this:

Then we will be very happy to answer the things that are not clear for you. :)

They are actually the reverse of each other.
