This assignment is a series of videos that cover the major concepts of Unit 3, there will be questions throughout the videos that you will need to answer to continue. These are not graded and are meant for self assessment, to help you gauge how well you are understanding the concepts. If you feel like you need more help with these concepts, let me know and we can schedule time for us to meet and go over them.

The easist way to look at this type of cross section is to start with the youngest rock, which we know is C, since it occurs in all the other levels of rock. Feature D interacts with rock C, and we can see if break though rock C, so it happend after rock C was formed. Now follow feature D down, it is interupted by feature A, for A to interfere with D, it would need to have occured after D was formed. If we keep going, we see feature E, which does not break Feature D, so it occured before D. This one is a little complicated, so it is okay for you to have gotten it wrong, it is more to help expalin how if you know one piece of informatoin (the youngest rock), you can use that to interpret a lot more from a geologic cross section.
