- The many questions raised by your post are all interesting, so
- much so that it is quite a tall order for the net to address them all.
- Perhaps a more concise form of question would be to try imagining what
- would happen to Earth's life if the Moon was suddenly removed.
- I believe this was once a question asked to prospective M.I.T
- PhD candidates at their written comprehensives.To start with,
- tides would cease along with major circulation patterns in the
- oceans, with the result of undesirable temperature variations
- which in turn would gravely perturb atmospheric cycles ...
