Many of the same principles are applied. But to use any trapped charge method, experts first need to calculate the rate at which the electrons were trapped. At time 3, layer 3 was deposited on top of layer 3. The cards in Set B represent rock layers containing various fossils.
Objectives: When you complete this activity, you will be able to: 1 sequence information using items which overlap specific sets; 2 relate sequencing to the Law of Superposition; and 3 show how fossils can be used to give relative dates to rock layers. Prospects of sequencing activity, it indicates the rocks and fossils, it is a geologic dating. Most of the events on the list could move up and down the absolute time scale quite a lot as we improve our calibration of the relative time scale. The volcanism pretty much ended halfway through the Moon's history.
