Relative and Absolute Dating Review

Scientists use radiometric dating (radioactive decay) to determine...

• relative time (dating)

• absolute time (dating)

• half-lives

• time of day

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

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

The amount of time it takes for 50% of the remaining radioactive material to decay into stable material is called:

• radiocarbon dating
• radioactive decay
• half-life
• successive decay time

By saying: "I am older than my sister," is an example of which type of dating used in Geology:

• Relative Age/Dating
• Absolute Age/Dating
• Chronological Sibling Timelies
• Fossil Age/Dating

The age of a rock compared to the ages of other rocks is the rock's

• absolute age
• geologic age
• sedimentary age
• relative age

By saying "my dad is 48 and I am 13", it would be...

• relative dating (time)

• absolute dating (time)

• law of superposition
