For this assessment, you will be identifying various rocks in much the same way as you did the minerals. You will use the information you learned in this module to complete the charts below. Remember to access the tips and hints below.

Basic Requirements (assignment criteria):

  1. You will need to use the rock identification charts with the chart, questions and images provided to help identify these rocks.
  2. You will use these documents to complete the lab. On the rock identification chart, their are different tabs for the different rocks. These tabs are located at the bottom and are listed: Igneous Rocks, Sedimentary Rocks, and Metamorphic Rocks.
  3. Complete the various columns for each rock type and answer the questions at the end. You will only submit the charts and questions only, not the entire document.
  4. Make sure your name is on the document before saving.
