Sedimentary rock occurs in layers and contains fossils. These layers and fossils were interpreted to make the Geologic Time Scale. From the relative dating of fossils, rock layers from around the world were put in order from youngest to oldest. 1. To create the Geologic time scale, what was interpreted?

The fossil record gives evidence of catastrophic events that occurred in the Earth's past. Some rock layers show a diversity of fossils, but sedimentary rock layers above these contain no fossils. Rock layers younger than these have fossils again, but the species are different. This indicates that a mass extinction has occurred. 2. In the Earth's past, the fossil record gives evidence of what?

The history of life on Earth is recorded in its fossils. Past environments are part of this history. Finding all the different types of fossils in an area gives a picture of the plants and animals that lived there. From this the past environment of the area can be determined. 3. What does fossil evidence allow scientist to describe?

A desert in Wyoming contains sedimentary rock layers with fossils. Many of these fossils are of amazingly well preserved fish. Fish live in water, so this desert was once a large lake or small sea. 4. Fossilized fish in the desert rocks of Wyoming is evidence for what?

The Geologic time scale has divisions These are eras and periods. The eras end with mass extinctions. The major divisions called periods end based on the appearance of new groups of fossilized species. So, the divisions of the of the Geologic Time Scale is based on major changes in fossilized life forms. 5. What was fossilized evidence of major changes in life forms used to determine?

The Geologic Time Scale contains three eras. These are the Paleozoic, Mesozoic, and Cenozoic. The Paleozoic and Mesozoic eras ended with mass extinctions. At the end of these eras, most species leave the fossil record. The Cenozoic era is the current era which has not ended. 6. On the Geologic Time Scale, what ends with mass extinctions?

We are alive. Eras in the Geologic time scale are marked with mass extinctions. We are part of the Cenozoic era. So the Cenozoic era didn't end with a mass extinction. 7. Mass extinction doesn't mark the end of which era?

Evolution theory is the idea that all life forms come from previous life forms. This theory maintains that life forms slowly change and diversify over time. This idea is that all living things came from the first living thing. Fossils of the Geologic Time Scale are interpreted to be over 3 billion years old. 8. According to the theory of evolution, When did life on Earth begin?

Radioactive elements change into other elements by giving off radiation. Rocks contain radioactive elements and the elements they turn into. By determining the ratio of these two elements give the absolute age of a rock. Radio active dating showed moon rocks to be 4.6 billion years old. The Earth is also this age. 9. What does radioactive dating lead scientist to believe?

Once you finish, compare your sentences with the items in assignment #38 on SNB pages 61 & 62.

Fossilized fish in the desert rocks of Wyoming is evidence that the desert was once underwater. 5. Fossil evidence of major changes in life forms was used to determine the major divisions of the Geo Time Scale 6. On the Geologic Time Scale, the end of each era is marked by a mass extinction. 7. We currently live in the Cenozoic Era and since we are alive, this era hasn't ended with a mass extinction. 8. According to evolution theory, life on Earth began more than 3 billion years ago. 9. Radioactive dating leads scientist to believe the Earth is 4.6 billion years old.
