Can somebody pleas help me with these Earth Space Science multiple choice questions? I don't understand this?

Please e-mail me. I can answer all of those questions, but I'm not going to do it here, because I know this is homework, and I do not want your to simply copy and paste my answers into your homework, because you probably will not give me credit as your source. Your teacher will know that you did not answer those questions on your own. I'm a planetary geologist/gephysicst. That's why I can answer these questions, and very few other people in Astronomy & Space can answer these questions. They don't have an almost master's degree in geophysics or a real master's degree in geology. I do. It's going to take a LOT of e-mails to go through all those questions. You can start your own research by doing a Google search on "seismic waves".
