The First Blog - a Big Crunch Thursday, April 10, 2008
    What? Me do a blog?  I thought blogs were for political wonks and other opinionated folks.  I'm a scientist and I'm supposed to be objective.  And that's probably boring.

    Or is it?  I'm a scientist because I'm curious about how the Earth works -- and  what I've learned is so exciting that I have never in 40 odd years felt bored.

    Here's an example:  Did you know that the huge pieces of real estate called continents are moving!  Yep.  If you live, say, along the eastern part of the North American  continent  you are moving toward San Francisco!  And pretty fast, geologically speaking.  Each year you will be about four centimeters closer to the Golden Gate Bridge!  That means you are moving about as fast as your fingernails grow.

    And there's more.  San Francisco isn't sitting still.  Riding on a big slice of western California, S.F. is moving north toward Alaska!  Now, when two parts of a continent  are moving in different directions there's bound to be a crunch, and that's what's happening along the San Andreas Fault in California.  Big Crunch.

    So, is the Earth an exciting place?  You bet.  And Earth Science is the process of discovering just how incredibly dynamic our planet is.

    Curious?  Send me an email with your questions:
