Unit E Section 3 Self-Check

Instructions


Complete the following 6 steps. Don't skip steps – if you do them in order, you will confirm your understanding of this section and create a study bank for the future.

  1. DOWNLOAD the self-check quiz by clicking here.

  2. ANSWER all the questions on the downloaded quiz in the spaces provided. Think carefully before typing your answers. Review the lessons of this section if you need to. Save your quiz when you are done.

  3. COMPARE your answers with the suggested "Self-Check Quiz Answers" below. WAIT! You didn't skip step 2, did you? It's very important to carefully write out your own answers before checking the suggested answers.

  4. REVISE your quiz answers if you need to. If you answered all the questions correctly, you can skip this step. Revise means to change, fix, and add extra notes if you need to. This quiz is NOT FOR MARKS, so it is perfectly OK to correct any mistakes you made. This will make your self-check quiz an excellent study tool you can use later.

  5. SAVE your quiz to a folder on your computer, or to your Private Files. That way you will know where it is for later studying.

  6. CHECK with your teacher if you need to. If after completing all these steps you are still not sure about the questions or your answers, you should ask for more feedback from your teacher. To do this, post in the Course Questions Forum, or send your teacher an email. In either case, attach your completed quiz and ask; "Can you look at this quiz and give me some feedback please?" They will be happy to help you!

Self-Check Quiz Answers

Click each of the suggested answers below, and carefully compare your answers to the suggested answers.

If you have not done the quiz yet – STOP – and go back to step 1 above. Do not look at the answers without first trying the questions.

One of the main reasons that Wegener’s idea of continental drift was not accepted by other scientists was that he could not explain how the continents had drifted. Two examples that Wegener might have used to explain moving pieces of Earth’s crust, also known as plate tectonics, are the Hawaiian Islands chain and the Mid-Atlantic Ridge seafloor spreading. These examples show how Earth’s crust is made of moving plates. This may have been enough evidence to convince the scientific community of Wegener’s ideas long before they were accepted.
The mountains appearing 300 million years ago formed when Laurasia and Gondwana collided to form Pangaea. The line of mountain ranges shows where the two smaller supercontinents collided to form Pangaea. Other evidence to confirm this includes coal beds found beneath and within these mountains and similar rock layers, folds, and faults in all these locations.
Location A is a transform boundary between the Pacific Plate and the North American Plate. As the plates move past each other, they can produce earthquakes but probably not volcanoes. Location B is a divergent boundary where the Nazca Plate is diverging from the Cocos Plate. This is a spreading ridge of seafloor. Location C is a converging boundary between the Caribbean Plate and the Cocos Plate. Because the Cocos Plate appears to be an oceanic plate, it probably is subducting under the Caribbean Plate and likely forming a volcanic arc of volcanoes somewhat northeast of the boundary.
The Galapagos Islands are located on the northern section of the Nazca Plate. This is a complicated tectonic area because several boundaries are nearby. This is similar to the triple-junction boundary that results in earthquakes off the BC coast near the Haida Gwaii islands. If the youngest Galapagos Islands are on the west end of the island group, and the Nazca Plate is moving east, then the oldest islands must be Espanola and San Cristobal.
The Rocky Mountains are an odd mountain range because they have volcanoes much farther inland from the zone where the ocean plate is subducted under the continental plate in normal fold-and fault mountains. The second image shows the idea that the ocean plate was subducted at less of an angle. Therefore, the volcanoes were formed further inland from the subduction zone than they are normally.
