In the great outdoor laboratory that most of us know as The Planet Earth people are working all the time to determine how mountains and canyons were formed, lakes are made and why volcanoes erupt the way they do.
They are studying geology. They also examine small and not so small changes that might help to predict the future. Geologists also study the Earth's resources, like minerals, gems, oil and coal, to help figure out where they are and how we can use them.
The National Geographic Society calls on all of us to recognize the importance of Geo-literacy.
In addition to great books about geology the Multnomah County Library has a couple of electronic encyclopedias that can answer many of your questions about the Earth Sciences. You will need to use your library card number and password to login to the Oregon Career Information Service, for detailed information about the occupation, or Kids Infobits.
If you love rocks, fossil hunting or trying to read the Earth's history from it's landforms, you might want to be a Geologist.
