Absolute/Relative Dating 22

Absolute age is defined as:

• The age of rock determined by radiometric dating.
• The age of rock based on living animals.
• The age of rock based on its location.
• The age of rock determined by carbon dating.

By saying: "I am older than my sister," is an example of which type of dating used in Geology:

• Relative Age/Dating
• Absolute Age/Dating
• Chronological Sibling Timelies
• Fossil Age/Dating

True or False: An intrusion and fault are ALWAYS younger than the rock they cut through.

• True: because the rock layers must be there initially - the fault or intrusion cannot occur in nothing.
• False: they are always younger.
