ERSC 1P01 –– Sedimentary Rocks ASSIGNMENT DUE 31 hours after your ‘IN PERSON LAB’ i.e. 11:55 PM the next day Objectives: The identification of the common sedimentary rock-forming minerals and recognition of the typical sedimentary rock textures, leading to the identification of the major types of sedimentary rocks. To learn how to interpret what is seen in sedimentary rocks in order to identify the depositional environment. Development of scientific observation and descriptive skills. General Instructions: 1. Go to the Lab Material>Lab 4: Sedimentary rocks page in Sakai. The two main Sedimentary Rock types will be explained and demonstrated further in mini-video demonstrations. A PDF document describing Sedimentary Rocks is also available for you to download. Make sure to watch each video to fully understand how to distinguish between the Clastic and Chemical/Biogenic types of Sedimentary rocks. The first step to to determining the Sedimentary rock name will be to determine what type of sedimentary rock you are observing. You may want to take notes as you watch the videos! 2. We will be reviewing the Sedimentary Rock types during the IN PERSON lab session. You may also bring your own laptop/tablet AND HEADPHONES to your IN PERSON lab sessions to rewatch and review the videos. There is ONE assignment question document provided for you. At the END of this document is a Sedimentary Rock Table which lists the questions in a TABLE format. 3. There are also Sedimentary ROCK ID TABLES provided for you in a separate PDF document. The TABLES contains information on how to identify each Sedimentary rock as well as overall descriptions for the sedimentary rocks. Use these tables to determine the SEDIMENTARY ROCK NAME! In addition there is a Sedimentary depositional environmental document that will also assist you with answering some questions. You may print the documents and bring paper copies to your IN PERSON lab OR you may wish to work directly from your own computer/tablet. (NOTE: Paper copies will NOT be provided in your lab session!) 4. Note: The descriptions in the SEDIMENTARY ID TABLES provide overall-general desciptions of the rock types. Make sure to descibe only what you see in the presented sample (do not add information that is not there or marks will be deducted).

1 ERSC 1P01 (Planet Earth I) – Sedimentary Rock lab (enter answers in Tests and Quizzes tool) *The sedimentary rock samples will be provided in your ‘IN PERSON’ lab session. You must attend your scheduled ‘IN PERSON’ lab session in order to answer the questions and submit this assignment. If you do not attend an ‘IN PERSON’ lab session but still attempt to submit answers to this assignment this will be considered a violation of Brock’s academic misconduct policy . SUBMITTING YOUR ASSIGNMENT AFTER YOUR IN PERSON LAB SESSION 1. The Sedimentary rock lab will become available for each individual lab section in the Test and quizzes tool at 5:00 pm on the day of your Scheduled IN PERSON lab and will be due by 11:55 pm the following day. 2. When you have answered all of your assignment questions you will then go to enter the answers in the ‘Test and quizzes’ tool. Every student will be answering a unique combination of thirty (30) questions randomly drawn from a bank of questions that you have just answered. You may save your answers and go back to answering them at a later time. However, if you ‘submit’ your answers and go back to ‘resubmit’ at a later time– you will be presented with an entirely new randomized draw of questions to answer! 3. Each IN PERSON lab section will also be given a unique set of five (5) questions to answer. The questions and associated igneous rock samples will ONLY be provided during the IN PERSON lab session. Assignment Questions REMINDER! Please answer all questions before entering your answers under the Tests & Quizzes section in Sakai. Each question is worth 1 mark. Total marks = 35 (30 mks from random draw of questions + 5mks for questions from each in person lab section). SEDIMENTARY ROCK Assignment Questions (This document is for rough work ONLY! This document DOES NOT need to be handed in! ONLY ANSWERS SUBMITTED IN THE “TEST AND QUIZZES” TOOL WILL BE MARKED) Answer the question for the specific SEDIMENTARY rock sample provided! How to answer questions in the ‘Test and quizzes’ tool? 1. Some of the questions will have ‘multiple choice’ answers available for you to choose from. ‘Click’ the correct answer from the list provided. 2. Some of the questions will require you to write in your answer in either a ‘short answer’ format. You DO NOT need to answer using sentences. ONE to TWO word answers are recommended! The following is the list of questions that you will be answering for this assignment. We have also provided you with a Sedimentary Rock Table at the end of this document.
