  13. Radar Image of NEO 1999JM8 Missed Earth by 5 million km in 1990, 6 million km in 1999 Average diameter 3.5 km

  14. Tunguska Event, 1908, Russia 80 million trees knocked down over 2,150 square kilometres (830 square miles

  15. Tunguska Event 1908 Equivalent to a 100 MT Nuclear Bomb Blast

  16. Question If cratering rate on Earth is same as our Moon, why are their so few craters preserved?

  17. What is wrong here?

  18. Apollo 14 site spherules (~ 0.2 mm diameter) Argon40/Argon39 dates (accuracy ~ +/- 200 MY)

  19. Apollo 14 site spherules (~ 200 micro-meters diameter) Argon40/Argon39 dates (accuracy ~ +/- 200 MY) => 26 Ma periodicity

  20. 1 BY averaging bins Black and opaque spherules only

  21. Question: If cratering rate on Earth is same as our Moon, why are their so few craters preserved? Answer: Erosion
