Since your classroom teacher is absent today, you are to review Section 3 that we had done on Monday by answering the series of questions that are based on the theory of Plate Tectonics as well as make a concerted effort by reading Section 4, Deformation of the Earth’s Crust, and reinforce it by answering the series of questions that are based upon it.
Chapter 4, Sections 3&4
Study Guide (Pages 108-118)
ANSWER THE FOLLOWING QUESTIONS ON A SEPARATE SHEET OF PAPER AND TURN IT IN WHEN YOU ARE DONE. DONOT WRITE ANYTHING ON THE QUESTION SHEET!
- Define the theory of plate tectonics.
- Identify the three plate boundaries. Explain each type of boundary.
- Why do tectonic plates move?
- What causes the changes in the density of the asthenosphere?
- List three factors that determine how fast tectonic plates move.
- How fast does a tectonic plate move per year?
- What do scientists use the global positioning system (GPS) for?
- How does a global positioning system work?
- How can scientists measure the speed at which each tectonic plate move?
- Define the term deformation.
- What is the outcome when two tectonic plates get compressed over time?
- What is the outcome when two tectonic plates undergo tension over time?
- Define the term folding.
- List and explain the three types of folding.
- Give an example of a real-life rock folding that is seen in nature.
- Define the term fault.
- How can we determine whether we see a hanging wall or a footwall?
- What happens when there is a normal fault? What type of stress is involved here?
- What happens when there is a reverse fault? What types of stress is involved here?
- Explain how you can tell the difference between a normal fault and a reverse fault.
- Define a strike-slip fault. Give a real-life example of it.
- How did the Andes Mountains form?
- How did folded mountains form? Give 3 real-life examples of it.
- Describe fault-block mountains. Give a real-life example of it.
- How does a volcanic mountain form? Where do we find most of them?
- Distinguish between uplift and subsidence.
- Define the term rebound. This can result during which vertical movement.
- How does the ocean floor subside?
- Define a rift zone.
- How does subsidence occur at the rift zone?
