Discuss relative absolute dating

Here is an easy-to understand analogy for your students: relative age dating is like saying that your grandfather is older than you.

Absolute age dating is like saying you are 15 years old and your grandfather is 77 years old.

You can test out of the first two years of college and save thousands off your degree.

Anyone can earn credit-by-exam regardless of age or education level.

For example, instead of pm we might say 'lunch time.' There is no definitive time for lunch, except that it occurs between breakfast and dinner.

So relative to the other meals, it falls in the middle and is later than breakfast yet earlier than dinner.

For example, 60 million years is a measure of absolute time. These are numerical representations of time, and they give us specific points of reference.

We have a long record of events in absolute time but much of that occurred before humans were on Earth to write it down.

But instead of saying that one layer is x number of years old, you can simply describe it as older than the layer above it yet younger than the layer below it.

How much of your life do you spend thinking about time? Time comes in different forms in geology, mainly absolute and relative.

They are both important in terms of Earth's history and its geological timeline, and they work together in concert to build the planet's geological record.

And when we put both absolute and relative time together, we create a geologic time scale that puts all these events in perspective. are layered in their relative order from oldest at the bottom to most recent at the top, and we also see how much absolute time each one spans.

For example, if we look at the scale, we see that the Paleozoic Era comes before the Mesozoic Era, relatively speaking, and that it spans about 290 million years, starting about 542 million years ago and ending about 251 million years ago.
