Today we reviewed the essential characteristics of the crust, lithosphere, aesthenosphere, mesophere, mantle, outer core, and inner core. I also showed them more images that showed the temperatures and the layer boundaries, the depths and thickness of each layer, as well as the composition of each layer. The homework is to read chapter 4.2 in the text and to answer the review questions at the end of the chapter, and the workbook chapter 4.2. Tomorrow their is very short quiz just on the different layers of the Earth's core. We reviewed extensively today for this so everyone should do well. Take care, and see you tomorrow, Mr. Woolsey.
