Plate Tectonics: Lines of Evidence

Science ObjectDigital resources are stored online in your NSTA Library.

Science Objects are two hour on-line interactive inquiry-based content modules that help teachers better understand the science content they teach. This Science Object is the fifth of five Science Objects in the Plate Tectonics SciPack. It explores the physical, geographical, and geological evidence for the theory of continental drift and plate tectonics. Plate tectonics provide a unifying framework for understanding Earth processes and history, and is supported by many lines of evidence. Over geologic time, plates move across the globe creating different continents (and positions of continents).

Even though I was searching for slope of a line material, this article appeared. I thought it would be interesting to read, and it was. I now have a better understanding of vault lines based upon the research that shows how all the continents once were connected, and not separated by large bodies of water. I never looked at how South America and Africa could of been connected until reading this article. This history of how the earth has been shaped was very enjoyable reading; research and investigation. I highly recommend this article for the novice when it applies to our planet.

This science object tied together the 5 part series describing all the evidence to support plate tectonic theories. Natural disasters are fascinating to students in the MS years, so this is helpful background for teachers to plan lessons.

I really enjoy Science Objects. In 1-3 hours, the Plate Tectonics: Lines of Evidence Science Object will help me re-learn, refresh, or learn for the first time some critical science concepts I will have to know to obtain my Science Educator credentials. I appreciate that I can complete them at my own pace, and that, if used as park of a SciPack, I have access to a content expert to go to for help. The NSTA Learning Center Science Objects are very beneficial! Not only will they enrich my teaching, the knowledge will enrich my life.

This fifth of five lessons on plate tectonics describes and explains the geologic, fossil, seismic, volcanic, and oceanic evidence which together support the theory of plate tectonics. The lesson is interesting and thorough in its overview of the subject.

This resource takes you back in time for a quick explanation of German meteorologist Alfred Wegener's proposition that the continents were once a large land mass (Pangaea), From the distribution of similar fossils and geologic formations across many continents, to the seemingly puzzle-like fit of the African and South American coastlines, we learn of the evidence to support the Continental Drift Theory. Very interesting!
