Relative dating geologic events

Learn how scientists determine the ages of rocks and fossils.We'll explore both relative and numerical dating on our quest to understand the process of geological dating.Discover how geologists study the layers in sedimentary rock to establish relative age.Learn how inclusions and unconformities can tell us stories about the geologic past.Your goal is to study the smooth, parallel layers of rock to learn how the land built up over geologic time.

And, what about other findings like fossil fish, plants and insects?In this activity, students begin a sequencing activity with familiar items — letters written on cards.Once they are able to manipulate the cards into the correct sequence, they are asked to do a similar sequencing activity using fossil pictures printed on "rock layer" cards.There are two techniques geologist use to obtain the Earth's age: Radioactive dating and Relative dating. The exposed rock reveals layers of different types of rocks.Geologists observe the geologic layers and try to reconstruct the sequence of events.PALEONTOLOGY, AND in particular the study of dinosaurs, is an exciting topic to people of all ages.Although most attention in today's world focuses on dinosaurs and why they became extinct, the world of paleontology includes many other interesting organisms which tell us about Earth's past history.Scientists are always spouting information about the ages of rocks and fossils. Well, they figure it out using two different methods: relative dating and numerical dating.Let's find out more about these geological dating methods in order to understand how Paul the Paleontologist can be so sure about the age of his dinosaur fossils.Geologists establish the age of rocks in two ways: numerical dating and relative dating.Numerical dating determines the actual ages of rocks through the study of radioactive decay.
