5. These special elements are found in rocks and can be used to help calculate the absolute age of the fossils/rocks:

• Helium and Hydrogen
• Radioactive Carbon and Uranium
• Iron and Magnesium
• We don't use elements to calculate the age of rocks

9. When would we want to use Absolute Aging?

• When we want to find the exact age of something.
• When we are comparing the ages of different things.
• When we want to find out how much radioactive decay has occurred.
• When we want to see which fossils are similar in size and/or shape.

10. Use the image to help answer the following question: Using relative aging, how old is the formation of the Earth's core?

• Earth's core is....older than the formation of the moon.
• Earth's core is....younger than the earliest fossils.
• Earth's core is....about 4.50 billion years old.
• None of the above.
