Usually due to erosion. Not all rock layers are in nice and neat straight rows. Many have features that cut entirely them. The teaching of crosscutting relations states that geologic features such as faults and intrusions are younger than the rock they cut through.
Uplifting Erosion At some future time deposition begins again. Observe the following video. It is an excellent example of unconformities and the 3 main categories.

Imagine braving the uncultivated heat for days or even weeks as you slap in the face for dinosaur bones. You find something extraordinary and dearth to know as much about it as you can. In this castigation, you'll learn how scientists determine the absolute age of materials. There are two main tenors determining a fossils age, relative dating and absolute dating. We define the rate of that radioactive decay in half-lives. If a radioactive isotope is said to must a half-life of 5, years that means after 5, years exactly half of it require have decayed from the parent isotope into the daughter.

20 May Geologists often need to know the age of material that they find.
