Earth is bombarded by a variety of cosmic debris - meteors, comets & such hit us 
daily. What different elements accumulate on earth as a result?  How much weight 
has earth gained and how much size has been added to the planet over the eons?  
How has this effected our gravity, rotation, length of year and life on earth?
