1.) 1.) In 6 or more steps, describe the formation and geological history of where you live or just North America in general. The steps must be listed with the oldest event on bottom and the most recent event on the top, thus in chronological order like the Geologic Time Scale. For each step include: the numerical age/age range of the geological event’s occurrence, a brief description of the geological event in your own words, and the APA intext citation of your source. Each step is worth 3.5 points total [1 point numerical age/age range, 2 points for geological event description in your own words, .5 point APA intext citation of source). (21 points total). HINT: Use Chapters 2, 13, 14 and section 22.5 from the textbook to complete this assignment.

The glaciers from the Canadian shield regressed southward as temperatures across North America begin to warm. As the glacial lobes retreated north, they left behind deposits of glacial till and carved out depressions that eventually became lakes.

2.) 2.) What was the main method of expansion/growth of the North American Continent on the west coast? (2 points)
3.) 3.) What is a broad area of exposed crystalline rock, which has not changed for more than a billion years called? (2 points)
4.) 4.) What was the name of the super continent that preceded the formation of North America. HINT: This was the super continent that broke up and the pieces were used to form North America and other continents of today. (2 points)
5.) 5.) What are the three types of plate tectonic boundaries? All three types of plate tectonic boundaries exist today and in the past, and all three have been used to shape all of the continents (including North America) and the changes we observe today. (2 points)
6.) 6.) Reference list, in APA format, of sources used for this assignment. And be sure that intext citations were included for all questions 1 through 5. [1 point total]
