How do the methods used to date fossils help in understanding the timeline of life on Earth?

• They allow for the precise measurement of the Earth's age

• They help correlate layers of rock with periods of time and evolutionary events

• They provide exact dates for all events in Earth's history

• They are only used for dating human artifacts

Match the following

• relative dating

• length of time required for half of the radioactive isotope to decay

• absolute dating

• used to determine the actual age of a fossil

• half-life

• determine fossil age by comparing its placement in layers of rock

What challenges do scientists face when dating fossils?

• Fossils are too easy to find

• Some fossils are too old for radiocarbon dating

• All fossils are the same age

• Fossils can talk and give misleading information
