History of Life on Earth

How will you differentiate between absolute and relative dating?

• Absolute dating gives a numerical age, while relative dating determines the sequence of events.
• Absolute dating cannot be used for rocks.
• Absolute dating is only used for fossils.
• Relative dating provides a specific date for an event.
