• Continents are stationary and do not move

• The Earth is broken into lithospheric plates that move due to convection currents

• none of the above

Which process would be most effective in determining the age of fossils embedded in rock?

• relative dating

• absolute dating

• use of index fossils

• use of core sampling

Which characteristic of carbon-14 dating helps scientists determine the approximate time a species became extinct?

• Carbon-14 is NOT present in more recent fossils

How does absolute age differ from relative age?

• only absolute dating indicates which rock is older than another
