Which is the most accurate method used in determining the age of a fossil?
It determines the age of the mammoth.
radioactive dating
The deeper layers are older than the shallow layers.
450-year-old sediments
The rocks are approximately the same age.
carbon-14 with a half-life of 5,700 years
Different rock layers can be determined to be the same relative age if they contain the same index f
absolute dating
A geologist found 600-year-old sediments below a particular rock layer. Which will the geologist most likely find above the rock layer?
It determines the age of the mammoth.
radioactive dating
The deeper layers are older than the shallow layers.
450-year-old sediments
The rocks are approximately the same age.
carbon-14 with a half-life of 5,700 years
Different rock layers can be determined to be the same relative age if they contain the same index f
absolute dating
A scientist finds an index fossil in layers of rock in both Africa and South America. What does this indicate about the ages of the rocks?
It determines the age of the mammoth.
radioactive dating
