About Us
Stratigraphy Sequence Tutor is an app to help you memorize the sequence from most recent to earliest of the Ages, Epochs, Periods, Eras, Eons & SuperEons. Additionally, there is a quiz to help you memorize how many years ago in sequence for the Ages, Epochs, Periods & Eras in named order from most recent to earliest.
As you select each timescale your correct answer will appear in the PickerRoll. You may roll through your correct answers to help you review and memorize the correct sequence of timescales and when you are ready to select the next timescale in the sequence then the PickerRoll will roll back automatically to your most recently chosen answer in the sequence and add the next correct answer to the list.
This app is an excellent study aid for students of geology, paleontology, archaeology, history & climate sciences.
