Welcome to Geosciences 10.
I'm Richard Alley, and I'll be your tour guide to the geology
of the National Parks.
In the course of the semester, we're going to visit some of
the most beautiful and interesting
places in the world.
We're going to ask some big questions.
Why are there mountains?
And volcanoes, and earthquakes?
Why are the mountains torn down by rivers, by glaciers?
What's the history of this planet?
How do we live on the planet?
How do we stay happy, and healthy, and
terrific with the planet?
And while we're doing it, we are going to visit some of the
most beautiful, wonderful, places on the planet.
At the end of the semester we're all going to know a lot
more about the National Parks, and you're going to be so
excited that next summer you're going to be off to
visit one because they're such wonderful places.
Have a great semester.
I'm going to jump on my bicycle and head in to school
and get to it.
