Relative vs Absolute Dating

If you found an index fossil in a layer of rock in Montana and a similar fossil in a layer of rock in Texas, you would know that:

• the fossils and rock layers are the same age

• the fossils from Montana are older

• the fossils from England are older

• none of the above

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

If the half-life of a radioactive group of atoms is 300 years, then how old is the rock if there have been three half-lives?

• 37.5 years

• 100 years

• 600 years

• 900 years

What is the main difference between relative dating and absolute dating?

• Relative dating uses the order of rock layers to determine age, while absolute dating provides numeric ages.

• Relative dating involves radiometric dating, while absolute dating involves stratigraphy.

• Relative dating is more accurate than absolute dating.

• Relative dating relies on isotopes, while absolute dating relies on superposition.

Which stable isotopes of carbon are commonly used in radiometric dating?

• Carbon-16, Carbon-17, Carbon-18

• Carbon-10, Carbon-11, Carbon-15

• Carbon-19, Carbon-20, Carbon-21

• Carbon-12, Carbon-13, Carbon-14

What is the law of superposition in relative dating?

• Older layers form on top of newer layers.

• Layers are always vertical.

• Layers are always horizontal.

• Newer layers form on top of older layers.

How does relative dating arrange events or objects in chronological order?

• By using the law of superposition and the order of rock layers.

• By measuring the ratio of isotopes in rocks.

• By studying the fossils found in rock layers.

• By analyzing the chemical composition of rocks.

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

Which type of dating method can be used on rock layers by applying the Law of Superposition?

• relative dating

• absolute dating

• radioactive dating

• radiometric 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
