Relative or Absolute Fossil Dating

The Law of Superposition helps scientists to determine what?

• The absolute age of rock layers

• The age of fossils

• The relative age of rock layers

• the super powers of rocks

Relative dating determines the

• precise age of fossils

• age of rock layers and fossils compared to others

• climate fossils survived in

• movement of continents

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

What is the primary difference between relative and absolute fossil dating?

• Relative dating provides a specific age, while absolute dating provides an age range.

• Relative dating provides an age range, while absolute dating provides a specific age.

• Relative dating uses radiometric techniques, while absolute dating uses stratigraphy.

• Relative dating is more accurate than absolute dating.
