PlateTectonics (HMWK tonight!)

HMWK tonight:  Read 362-369.  On p. 369, #1-7.  For #6 and #7, please change the numbers in your book. Use P waves @ 8km/s and S waves @ 4km/s.  Feel free to fix this in pen - will prevent future troubles for me!

FRIDAY:   Competition for bonus points:  Name the most tectonic plates out of your class.  There are 7 major plates, many small plates, and lots of microplates.  All are fair game.  You must memorize and then write from memory in the competition.

In class today:  Reviewed how waves provide the bulk of evidence for what we know about the Earth's interior (from yesterday).
Watched a couple of video clips on subduction zones, convergence, and earthquakes as well as divergent plate boundaries forming new oceanic plate at a mid ocean ridge.
Took notes and discussed plate tectonics.
Get a copy of notes (with images) here.

Several classes also got answers to last night's homework.  Will finish tomorrow if not.

Tomorrow we'll continue notes and discuss answers to homework from today and tomorrow.

Friday Mrs. Greene (Honors Chem I teacher) will come give you your algebra quizzes back and speak to you regarding Honors Chemistry to help you decide if you are interested in the challenge.

Afterward we'll have our plate - naming competition and work some problems involving wave speed and P-S lag time to prepare for next week's work when we locate earthquake epicenters!
