Unit 4 Test Review

Which isotopes are useful when finding the absolute ages of rocks and fossils?

• Uranium is useful for dating rocks and carbon-14 is useful when dating fossils

• Uranium is useful for dating fossils and carbon-14 is useful when dating rocks

• any isotope can be used to date rocks and fossil

• Iron is used to date both rocks and fossils

Principle that Earth's processes occurring today are similar to those that occurred in the past 

• unconformities 
• uniformitariansim 
• superposition

What is the law of superposition?

• The age of sedimentary rock not found in the original layers.

• Metamorphic rock is younger than the nearby igneous rock.

• Sedimentary rock in it's original position is older than layers above it.

• Metamorphic rock is older because it was deposited to nearby sedimentary rock.
