He could be pretty confident that his super awesome dinosaur was about 175 million years old.

Scientists piece together a story of how one event came before or after another.

Relative dating cannot tell us the actual age of a rock; it can only tell us whether one rock is older or younger than another.

For example, if an area used for trash has modern refuse in it such as CDs and computers, and the layer underneath has cans made of tin, then it is safe to say the layer of tin cans have a greater relative age than the layer with modern refuse.

The key in relative dating is to find an ordered sequence.

The most common form of relative dating is called stratigraphic succession.

This is just a fancy term for the way rock layers are built up and changed by geologic processes.

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.
