The table below shows the assignments you must complete and how they'll be incorporated into the overall grade. Geology 101 consists of short video lessons that are organized into topical chapters.
Each video is approximately 5-10 minutes in length and comes with a quick quiz to help you measure your learning. Watch lessons on your schedule whenever and wherever you want.
The discovery of radioactivity and its application to dating rocks is perhaps one of the greatest scientific achievements affecting the Earth Sciences.
With the discovery of radioactive isotopes more then one hundred years ago, scientists quickly realized that the radioactive decay of materials found in rocks could be used to date the rocks and consequently change the "relative" geologic time scale into an "absolute" time scale.
Your grade for this course will be calculated out of 300 points.
