Question 1 – worth 8 marks 

Using the three different rocks, granite, shale and schist, as well as the rock cycle, answer the following questions:

  1. Can these rocks become one of the other through geological processes? (2 marks)
  2. Describe the processes involved and the evidence you would use to support your claim.  You can use drawings to illustrate your answer. (6 marks)

Question 2 – worth 10 marks 

The following diagram (Figure 4.1) shows four crustal plates (two continental and two oceanic plates), the boundaries between the plates (numbered 1 through 3) and the location of a volcanic arc.  Based on the diagram, answer the following questions:

  1. Boundary 1 is a convergent boundary.  In what directions are Plate A and B moving from? (Use cardinal directions in your answer) (1 mark)
  2. A volcanic arc is located on Plate D therefore Boundary 3 must be what type of plate boundary?  (1 mark)  Explain what is happening along that boundary to produce the volcanic arc. (3 marks)
  3. Boundary 2 must be what type of plate boundary?  (1 mark)  Describe the direction of movement for Plates B and C, and the features that must be located at that boundary. (4 marks)

Figure 4.1 Schematic of various plate boundaries.

Question 3 – worth 5 marks 

Visit the website Volcano World (http://volcano.oregonstate.edu/). Look through the volcanoes and select a North American volcano. For the volcano you selected, answer the following questions:

  1. Name the volcano you selected.
  2. State whether the volcano is a strato- or shield-volcano.  Describe the appearance and other characteristics of that type of volcano (i.e. type of magma, structure, etc.). (2 marks)
  3. Using maps found in your textbook, choose the geologic setting of the volcano.  Is the volcano located (i) along a ridge (i.e. divergent plate boundary), (ii) near a trench (i.e. convergent plate boundary) or (iii) in the middle of the plate away from a ridge or trench (i.e. hot spot)?  Explain why the volcano should be located in that setting including the plates that are responsible for the formation of the volcano. (3 marks)

Question 4 – worth 5 marks 

Label the following diagram (Figure 4.2), indicating for each blank space the type of mass wasting processes that would match the conditions listed.  Use the list of mass movements in the instructional content. (5 marks)

Question 5 – worth 8 marks  

  1. Describe how a point bar and cut bank form and develop in a fluvial environment (4 marks)
  2. Explain (in your own words) the evolution from a meander to an oxbow lake (4 marks)
