Day 6: Layers of the Earth and Convection Currents

Today we finished talking about the layers of the earth and discussed the evidence that we have used to construct the earth as we know it.  Using S, P and Surface waves, geologists have determined the states of matter of each of the layers of the earth.  I would like you to write you second draft based on this information.  Here is an outline for the draft:

1. Introduction
1. We have always been told there are layers of the earth, how do we know this to be true?
2. What are the layers of the earth and what is the state of matter of each (and why are those different layers either solid or liquid?)
3. Earthquakes provide evidence in the form of seismic waves.  State the properties of each of the following types of waves:
1. s
2. p
3. surface
2. Evidence
1. What evidence do s and p waves give us in the velocity chart?
2. What evidence to s and p waves give us in the zone graph/map?
3. Do these two pieces of evidence support each other?  (how)
3. Conclusion
1. Given what you have stated above, is it safe to say that there are indeed layers of the earth?
2. Would you like any other evidence or are you convinced?

This draft is due the Monday after we come back from our trip.
