Radiometric dating helps us find a absolute date for the fossils which is a more precise way of finding out when these organisms lived.

# data[].attributes.body
By looking at rock layers, we can tell how old fossils are and when they lived. The lower the rock layer is, the older the fossil is and the higher the rock layer is, the younger the fossil is.

# data[].attributes.body
The lower layers of rock are older and the most recent layers are youngest

# data[].attributes.body
rocks can be used as a time line the bottom is oldest top is newest.

# data[].attributes.body
Scientists use radiometric dating to find the accurate ages for particular layers of rocks.

The law of Superposition helps us find the Relative dating of rocks in the layers with the oldest on the bottom and the youngest on the top layer.

Fossils buried within the rock layers are evidence for the events that occurred throughout history.

# data[].attributes.body
There are many layers of rock and the layer at the bottom is the oldest rock and the layer at the top is the youngest rock. This is called the Law of Superposition.

Earth is billions of years old, and there were many important time periods and events that happened  during those billions of years that fossils can help us learn more about.

# data[].attributes.body
The earth's history dates back to around 4.6 billion years ago. The Law of Superposition does not determine the exact age of rocks.

By looking at events in order,  we can see how some events connect and differ.

# data[].attributes.body
All the events show us connection between each event.

# data[].attributes.body
There is many events that happen through out earths time.

# data[].attributes.body
reading the book of the history of earth, it would take one page every 2 minutes and 17,503 years to finish.

# data[].attributes.body
the history of earths past goes very far back throughout the major events and time periods  we can tell this by looking at relative dating by looking at rock layers.

# data[].attributes.body
Timelines can be used to show relative order between a series of events ranging from youngest to oldest or vise versa. Fossils from billions of years ago become buried within the rock layers to provide evidence for earth's history.
