Earth's History

Resource used: Discovery Education & 'Science' Text

Your Study Guide  is compiled on this page. Study guide completion is a mandatory assignment collected the day of the test.

Rewrite each question in your notebook in the question column, research the answer using your NTBK or DEducation.

Unit: Earth's History
Concepts: Fossils and Studying Earth's Past- If you want to know about life on Earth millions of years ago, check out fossils, remains of plants and animals that have been preserved in sedimentary rock. Only a small number of species survive as fossils, which include preserved footprints, and burrow molds.

  1. Why is it important to study geologic time?
  2. How could the same land species have gotten from one part of the world to another. (Define Terms: continental drift, seafloor spreading, platetenconics)? Bill Nye
  3. What explanation did Wegner construct to explain how identical plant and animal fossils could have gotten from one part of the world to another? Wagner-Reading passage
  4. Why do you think the scientific community was resistant to accept his ideas? Wagner- Reading passage
  5. Was the evidence that Wegner had valid and reliable?  Wagner-Reading passage
  6. What are the different types of divisions of geologic time?
  7. What is a fossil?
  8. How do scientists determine the absolute age of a fossil?
  9. How do scientists determine the relative age of a fossil?
  10. How do fossils show how organisms have evolved through time?
  11. How do fossils provide evidence of environmental changes that occurred in the past?
  12. What is a mold?
  13. What is a cast?
  14. What is amber?


Class Lab Webquest on Fossils, I gave you the worksheet this is a digital copy to access the webpages easiler.

Please know I would assess you the items that are circled on your paper lab on Thursday's test.

This lab activity will be completed entirely on-line.  You will be visiting several web sites devoted to fossils, the fossil record, and geologic history.  Visit the web sites listed and explore the information presented.  As you do so,record brief responses to the questions below.  This activity will be collected and counted as a lab.

Destination #1: “Getting in to the Fossil Record”
Click the links at the bottom of the page to continue through the site. Some pages may require you to click on an image or answer a question before the link appears to guide you to the next page.

Destination #2: “The geologic Time Scale in Historical Perspective”
