EVIDENCE OF CONTINENTAL DRIFT ACTIVITY

  1. Please put the following maps in order to show how Earth has changed over time. Please write a 1 next to the earliest map and go up to 5 and show me the modern map of the world.

  1. Now that you have put the maps of the world in order, it is now time to put Pangaea together. Use the puzzle pieces that I have given you to put this map together. Use the legend below to help you. You are going to arrange the puzzle pieces in order to show the map of Pangaea then I want you to draw a sketch of Pangaea below by using your puzzle pieces that you put together. Show me your map before you move on.

______I understand that the continents appear to fit together like a puzzle.

  1. Let’s start to examine some of Wegener’s evidence of Continental Drift. Before we do this, we have to have another look at the Internal Structure of Earth. Please draw a diagram below that shows the following:
  2. Inner Core
  3. Outer Core
  4. Mantle
  5. Crust
  6. The Moho
  7. Asthenosphere
  8. Lithosphere

Checking your understanding!

  1. The Inner Core is made up of (solid or liquid) material.
  2. The Outer Core is made up of (solid or liquid) material.
  3. The ______is plastic-like material that is located below the solid part of the Mantle.
  4. The ______serves as a boundary between the Crust and Mantle.
  5. The ______consists of the upper part of the Mantle and the Crust.
  6. Oceanic Crust is (thicker/thinner) than Continental Crust.
  7. Oceanic Crust is (older/younger) than Continental Crust.
  8. The study of earthquakes or ______had led us to our modern day understanding of the Internal Structure of Earth.
  9. ______is the transfer of energy by the flow of a heated substance.
  1. Drifting Continents
  2. What is currently happening to the Volcanic Islands in Hawaii?
  1. What is happening to Mount Everest right now? Why is this occurring?
  1. Wegener proposed a hypothesis that supported the idea of ______or the fact that the continents were all one big massive supercontinent called ______
  2. This massive supercontinent began to break up approximately ______years ago.
  3. Wegener noticed that mountain chains had consisted of similar rock types. How can we explain these similar rock types even if there is an ocean in between the continents?
  1. This evidence led Wegener to believe that the continents were once ______.
  2. How did Wegener explain the presence of Kannemeyerid and Labyrinthodont on separate continents?
  1. How did he know that continents were once connected based upon fossils of these two organisms?
  1. How did Mesosaurus help Wegener to prove his idea of Continental Drift?
  1. Why did Glassopteris exist on several continents when Wegener was researching?
  1. What did Wegener conclude about the climate in which Glassopteris must have needed in order to grow?
  1. Why did Wegener believe that Antarctica was not always frozen over?
  1. Where did he believe Antarctica to be in its’ geologic past?
  1. What two questions was Wegener not able to answer that led to his hypothesis being rejected?

Complete the Discovery lab on Page 443 in the textbook. Be nice to Mrs. Shelton’s rulers.

  1. What is the actual distance between San Francisco and Los Angeles.
  1. At the current rate of movement, when will these two cities be next-door neighbors?
  1. What might be causing these large pieces of land to move?
