A good way to introduce the concept of rock sequencing is to present each step with a separate sketch. We usually just give students the finished product and many students have trouble with seeing how the finished diagram came to be. Here are a couple of good sequencing games.

This glossary of geology is a list of definitions of terms and concepts relevant to geologyits sub-disciplines, and related fields. For other terms related to the Earth sciencessee Glossary of geography terms. Also called Indianite. Also called a composite gem.
Here I want to concentrate on another source of error, namely, processes that take place within magma chambers. To me it has been a real eye opener to see all the processes that are taking place and their potential influence on radiometric dating. Radiometric dating is largely done on rock that has formed from solidified lava.

Nicolaus Steno introduced basic principles of stratigraphythe study of layered rocks, in William Smithworking with the strata of English coal Former swamp-derived plant material that is part of the rock record. The figure of this geologic time scale shows the names of the units and subunits.
Relative dating is used to arrange 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. Relative dating does not provide actual numerical dates for the rocks.
What was missing from the early geologic time scale? While the order of events was given, the dates at which the events happened were not. With the discovery of radioactivity in the late s, scientists were able to measure the absolute ageor the exact age of some rocks in years. Absolute dating allows scientists to assign numbers to the breaks in the geologic time scale.
