Earth Science Presentations

Below are the presentations I used in class this month.


Today's assignment: Read through each presentation and post a comment at the end. Take your time, this should take you 20 - 30 minutes. 


Your comment should include one thing you learned, one thing you remembered, and one question you still have. 


When you are finished, check out stuff on the rest of this blog or research Earth science topics on your own. This is your time to study for tomorrow's test, not free computer time.

Is a Geomagnetic Reversal coming? Will it happen in 2012? Will this be the end of the world? Ask a physicist.
