Relative age dating activities

16 Feb

Scientists also use direct evidence from observations of the rock layers themselves to help determine the relative age of rock layers.

Specific rock formations are indicative of a particular type of environment existing when the rock was being formed.

Locally, physical characteristics of rocks can be compared and correlated.

On a larger scale, even between continents, fossil evidence can help in correlating rock layers.

Sequencing the rock layers will show students how paleontologists use fossils to give relative dates to rock strata.

Extinction of species is common; most of the species that have lived on the earth no longer exist.

*Earth and Space Science: Fossils provide important evidence of how life and environmental conditions have changed.

The complete "Paleontology and Dinosaurs" module takes approximately four weeks to teach. " activity is a 30-minute introduction to geologic time.

This interactive asks you to use your knowledge of relative dating. Help us work out the relative ages of the layers of sedimentary rocks.

You need to work out the order in which rocks were formed, from youngest to oldest. Remember that younger sedimentary rocks lie on top of older ones and were horizontal when formed.
