Whatever you learn in any one day in this course you are likely to read about next morning in the local newspapers. The most important objective of the course is to make you aware that you live on a dynamic, ever changing, Earth. Sometimes these changes are violent and can endanger lives and property, others are so slow that a hundred life-times will not be enough to notice the most minute change.
Human life is lived on another time scale entirely.
An apple turns brown in a few minutes. Silverware turns black in a few days. A compost heap decomposes in a season. A child grows up in a decade. None of these everyday experiences prepares people to be able to imagine the meaning of eighty million years.
