Geologic Time and Relative Dating Review

A principle that states that younger rocks lie above older rocks if the layers have not been disturbed.

• Relative Age Dating

• Superposition

• Original Horizontality

• Cross Cutting Relationships

What does relative age tell us about a rock layer or fossil?

• The age of one rock layer or fossil compared to another.

• The relative age of a fossil determined by radiometric dating

• Younger rock layers sit on top of older rock layers

• Older rock layers sit on top of younger rock layers

This timeline of Earth's history is out of order. Rearrange each event so the order is correct, with the oldest event at the left of the timeline.

• More complex multi-celled life forms, such as underwater plants, start to develop.

• Earth starts to cool down, and its atmosphere, or outer layer of air, starts to form. Oceans and small, single-celled life forms like bacteria start to form, too.

• Dinosaurs everywhere! Lots of large land plants, too, and we start to see huge forests.

• Complex sea life, such as fish and other underwater animals, start to spread. The first trees start to appear on land, too.

• Gravity pulls together leftover matter from the formation of the Sun. Lots of objects nearby are crashing into each other. Earth is very hot, and mostly made of molten (melted) rock. Nothing is living here yet.
