1 Geology 3620 Exam 1 Team Questions (1) I restructured/changed or even added some questions and did not use some questions submitted because some teams set questions from sections assigned to other teams, or those questions were badly structured. Some of these questions may still be restructured or combined in the exam. (2) Only one answer per question. (3) Refer to question guidelines to search for answers; several are in your textbook.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
