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

• absolute age
• geologic age
• sedimentary age
• relative 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
