Ask A Scientist: Did a Comet Crack the Earth?

March 4th & 5th, 2008

COSMIC BULLSEYE! Among all the space rocks that have slammed into our planet, Dr. Vicki Hansen of the University of Minnesota Duluth and McKnight Presidential Professor of Earth and Planetary Sciences recently suggested that one asteroid (or several) might have set Earth's crust in motion. Join Dr. Hansen to discuss her controversial theory and why plate tectonics makes life on Earth possible.

20 W. Wisconsin St., Grand Marais

Wednesday, March 5, 7:00 – 8:00 p.m.
