Geologic Dating

Absolute age is defined as:

• The age of rock determined by radioactive dating.

• The age of rock based on living animals.

• The age of rock based on its location.

• The age of rock determined by relative 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
