Earth's magnetic field wanders around
Bring books
Homework from previous class due.
We go over the homework in class, then watch the NOVA earthquake video. Your assignment: come up with 15 questions related to the video.

Plate Tectonics
We skimmed through Chapter 10 in Holt, then I made an assignment for specific people (signed up on board) to build models out of cardboard of the following earth structures:
Sea floor spreading (p. 243, 266, 245)
Puzzle of plactes (p. 244, 248)
Convergent subduction zones (p. 250)
Transform boundaries (p. 251)
Convection (p. 252)
Terranes (p. 256) - if you are absent, you'll do this one
Pangaea - Gondwanaland (p. 258-259)
Interior structure of the earth (look it up)
Project is due on Tuesday. December 13.
In addition, I gave the following as homework and asked you to work on it in class:
Page 262 #1 - 16.

Internal structure of the earth and how we know it
Terminology and definitions of
the core
the mantle
the crust
convection
evidence for the iron core of the earth
the earth's magnetic field
composition of the earth by element
how we know the core exists: analysis of earthquakes
s waves and p waves
Most terrestrial rocks are nearly Poisson solids, for which the ratio Vs/Vp is close to the square root of three. In subtracting the arrival time at a seismograph of the P wave from the arrival time of the S wave (to find the S-P time ), this fact means that you can multiply the S-P time by a factor a 8 km/s to get a generally reliable estimate of the distance of the earthquake from the seismograph.
