Relative age of rocks is when you describe the age as_____________

• Numbers

• More crystalized

• Having more fossils

• Younger and older

You want to decide the absolute age of the fossil at the top, which of these statements is right? " Be careful absolute age!)

• The fossil at top layer is younger that the one at the bottom

• The fossil at the top lived between 60 and 200 millions years ago

• The fossil at the top is 500 million years in age

• It is not possible to know because there is no way to tell the absolute age of the rocks surrounding it
