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

• absolute age

• geologic age

Relative age is different from absolute age because

• relative age compares rock with surrounding rock while absolute age is how many years since the rock was formed

• relative aging is more accurate than absolute aging

• absolute age compares rock with surrounding rock while relative age is how many years since the rock was formed.

• Relative age is used to determine rock age and absolute age is used to determine age of fossils
