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

Relative Dating dates rocks __________
Absolute Dating dates rocks __________

• exact age; sequence
• sequence; exact age
• exact age; parent isotopes
• Laws; Isotopes

About how old are the oldest fossils of living organisms?

• 3.5 billion years old
• 3.5 million years old
• 4.6 billion years old
• 6,000 years old

A period of geologic time can be recognized by its respective ________________.

• Index Fossils

• Water

• Air

• Sand

Earth is approximately 4.6 billion years old. How do scientists determine this?

• measuring the age of the oldest fossils

• measuring the age of the oldest glaciers

• using radiometric dating techniques on meteorites

• determining the chemical composition of sea-floor sediments

If the same index fossils are found in different rock strata miles apart, what is probably true about the rock layers?

• The rocks are probably the same age.

• The age of the index fossil is 8 days old

• The rock layer is made of granite

• The rock layer is siltstone
