Now we’re going to ask for your input on the lab. What was the best part of this lab? This can be the most fun part, the most helpful exercise, or just your favorite thing about the lab. What aspects of this lab were the most confusing to you? Other comments about the lab? Now that you have completed this week’s lab, consider ConcepTest question #2 for this week. Would you answer the question differently now? Has your understanding of the topic changes now that you’ve worked through these activities? Review what you wrote in the “initial thoughts” box. In the space below, compare your pre-conceptions to what you know now after participating in the lab.

Lab #3: Sedimentary Rocks and Depositional Environments 47 Lab #3: Sedimentary Rocks and Depositional Environments The purpose of today’s lab is to introduce you to sedimentary rocks. By the end of the lab you should be able to distinguish between different sedimentary rock types and interpret their depositional history. Objectives 1) Know the processes through which sedimentary rocks form. 2) Be able to identify common sedimentary minerals. 3) Be able to identify common sedimentary rocks. 4) Be able to interpret the origin of sedimentary rocks on the basis of their texture and composition . 5) Be able to create a geologic history by interpreting a sequence of sedimentary rocks. Materials Pencil (no pens) Textbook Calculator (Homework) Pre-lab work (to be completed before lab begins) Complete the online Warm-Up Quiz using the information in this lab and your textbook, as well as the web links provided on the Canvas site. The ConcepTest will be on material related to igneous rocks from lab 2 and reading material from lab 3 (this lab). In-Class Activities (due by the end of lab today, requires a TA check) Activity 1: Depositional environments Activity 2: Geologic rock record Activity 3: Sedimentary rocks Homework Activities (due the beginning of next lab) Activities on pages 59-64

Lab #3: Sedimentary Rocks and Depositional Environments 48 Sedimentary Rocks The interaction of pre-existing rocks with the hydrologic cycle at the Earth’s surface results in the formation of sedimentary rocks. Sedimentary rocks typically form in layers, such as the colorful layers exposed in the Grand Canyon. Locally, the Chuckanut Mountains consist of sedimentary layers of conglomerate, sandstone, siltstone, and coal.

    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.
