Asteroid: Earth Destroyer or New Frontier pdf

Patricia Barnes Svarney is an award-winning science and science fiction writer--with more than three dozen published books for the general audiences. A native of upstate New York, she did field work in geology, but soon found out she had a knack for explaining and writing about topics in the various sciences. So she took up the pen (and then quickly learned to type when computers took over) and hasn't looked back since. Never one to be "pigeonholed," her books and magazine articles cover such topics as geology, mathematics, astronomy, forensic science, women's health (including books about diabetes and nutrition), the space program, humor, Star Trek, Sabrina, and Alex Mack--with even a few mentions of cats along the way.

Asteroid: Earth Destroyer or New Frontier pdf by Patricia Barnes Svarney

It would take an asteroid the size of Vermont crashing into the Earth to wipe out all life on our planet. We can probably go to sleep tonight without worrying about this happening. Yet a significantly smaller asteroid -- say, one that spans 10 football fields -- could wreak enormous damage on life as we know it. Even if it struck in the middle of an ocean, violent flooding could drown millions of people. Asteroids this size pass between the Earth and the moon with disturbing frequency, writes Patricia Barnes-Svarney. This book nicely combines history, science and engaging speculation. It's a must-read for doomsday aficionados.
