Geology
Good morning. *glances over the class* I'm not sure what, if anything, happened this weekend but if any of your classmates has gone missing, please let me know. Coffee and snacks are near the back and please don't forget to sign the roll sheet.
In our study of geology, et the environment has had a controlling effect on the nature of rocks since Precambrian times. When we examine a rock, a number of characteristics tell us a great deal about the way the rock was formed, even if the rock is a million, a hundred million, or a billion years old. The texture of a rock and the boundaries between the grains of minerals contained in the rock give us key information about whether the rock is sedimentary, igneous, or metamorphic. Other clues tell us much about the parent rock, or magma from which the rock was created.
In this exercise you will be asked to select a rock from your campus area and write a short geologic history in which the origin of the rock and the environment of origin is described and supported by evidence found in the rock itself. You will also be asked to observe the rock's present-day environment and make some speculations about what type of rocks will be found there ten million years from today.
Pair up, take a handout, and complete the lab. You have two hours and no, you may not go into town during this time. I will be watching.
