Geologic Time Review 24

According to the law of superposition, the oldest fossils are found 

• At the top of the rock layers
• Near the bottom of the rock layers
• In the middle of the rock layers
• Somewhat near the surface

How does absolute age differ from relative age?

• only absolute dating indicates which rock is older than another
• only absolute dating finds the age in years
• only relative dating finds the age in years

Geologists use radioactive dating to determine THE ABSOLUTE AGE OF ROCKS.

• True
• False

Scientists use radioactive dating to measure...

• relative time
• exact age

• half-lives
• time of day

A process by which scientists can determine the absolute age of a sample by examining the radioactive isotopes within that sample is called

• RELATIVE dating

• RADIOMETRIC dating

• Great guessing

• Chemical gradiation

States that younger rocks lie above older rocks if the layers have not been disturbed

• Law of crosscutting
• Law of superposition
• Relative Dating
• Unconformity

Used to determine whether an object is older or younger than other objects

• Superposition
• Relative Dating
• Fossil
• Unconformity

How do geologists use relative dating?

• Placing rock layers order from youngest to oldest

• Placing rocks in order by minerals they contain
• Classifying rocks by different textures
• Classifying rocks by different isotopes
