I'm working on a business exercise and need an explanation and answer to help me learn.
For this activity you will need to watch the short video(s) for each metamorphic rock. You have been provided with key characteristics for each metamorphic rock on the page with the metamorphic rock videos. You will need to identify each metamorphic rock by comparing that information with the table below to determine the rock name. Once you have determined the rock name you will need to create an excel table with the following columns and in this order:
Sample Number, Texture, Protolith/Parent Rock, and Name. You will be submitting this completed excel table. You need to put the samples in numeric order in the chart.
Each sample is worth 3 points.
You will use the chart below to determine the rock name.
