Movement of Earth’s Plates
(7th) Chapter 8-4 Cornell Notes

2. Chapter 8-4 Key Questions
How does the theory of plate tectonics explain the movement of Earths landmasses?
How has the movement of Earth’s plates affected organisms?

3. Chapter 8-4 Key Terms plate- theory of plate tectonics-
continental drift-

4. Chapter 8-4 Paragraph 1 crust: Earth’s rocky outer layer;
consists of dozen+ major pieces called plates ;
doesn‘t always follow continental boundaries;
some under ocean or may have both ocean/continents.

5. Chapter 8-4: Performance Task
Performance Task: Please turn to your partner and describe the difference between a “continent and a tectonic plate”.

6. theory of plate tectonics: Earth’s plates move slowly/various directions;
may “pull away”, “push toward”, or “slide by”;
theory states that plates move so continents move;
continental drift: slow movement of continents.
Chapter Paragraph 2

7. Chapter 8-4: Question The Theory of Plate Tectonics states that:
1. Earth’s plates move quickly much like the rotation of the planets.
2. Earth’s plates move slowly each year traveling in various directions.
3. Earth’s plates move slowly in one direction: counter-clockwise.

8. Chapter Paragraph 3
movement of plates/continents affected evolution;
location of organisms changes;
change in location = change in climate;
climate enormous influence on species development.

9. Question: Which of the following is a result of the movement of tectonic plates and the continents (2 answers)?
Chapter 8-4:
Question
1. Change in location.
2. Change in climate.
3. Change in mutation effects.
4. Change in water levels.

10. Chapter 8-4 Paragraph 4
Brachiosaurus fossils found on various continents;
therefore continents must have once been joined.

11. Chapter Paragraph 5
continental drift also affects organisms today;
with separation comes change in DNA makeup;
eventually become different species.
