Rock layers and relative
Explore how these methods contribute to forming the geologic time scale, helping us reconstruct Earth's history. Most sedimentary rocks are laid down in flat, horizontal layers. These can later tilt and fold due to tectonic activity, and river cuttings can cause gaps among the layers. Relative dating arranges geological events — and the rocks they leave behind — in a sequence. The method of reading the order is called stratigraphy layers of rock are called strata. In this activity, students observe rock layers located near Whanganui, watch an animation about how they were formed and use relative dating to work out the order in which rocks were created. Use this interactive to work out the relative ages of some rock layers from youngest to oldest. Painted Canyon Home Page
This section highlights animations, images, interactive graphics and videos used to teach the concept of geologic time in an introductory geology course. The links below are animations illustrating the principles of relative dating determining the sequence of events and to images of real examples on which to try out the principles.
