A. In class create with play-dough 10 MARKS:
1. Anticline
2. Syncline
3. Monocline
4. Dome
5. Basin
6. Plunging Syncline
7. Plunging Anticline
8 Overturned Fold
This assignment can be completed at home, but you must provide
your own play-dough and then bring models to class.
B. In class play with the geological compass to measure strike and
dip; then go on the field trip. 5 +5 = 10 MARKS
4. Project
-see 3D Model of Internal Process/Plate Tectonics
5. Test
3D Model of Internal Process/Plate Tectonics
(an option here is to create a Video Presentation)
Two Components required:
I. Visual
Key Items:
1. Title
-must include PLO #’s
2. 3D model
-2D images may be used, but there must be a 3D component
-in short, the more 3D/hands-on, the better
3. Terms
-images are labeled with geological terms as given in PLO’s
See Assessment Master 11 ‘Creating a Display’ Marks = /24
II. Presentation
Key Items:
1. Title
-must include PLO #’s; that is, it must be clear what we are trying to
learn from the presentation
2. Length
-varies according to need, but minimum 5 minutes
3. Terms
-key ideas are explained by using the model
See Assessment Master 13 ‘Giving an Oral Report’ Marks = /14
Total Value = /38 marks
Note: If you choose the video option I believe the above marking scheme still
applies.
Steps:
1. Review PLO’s/Brainstorm/Assign Topics
2. Research Topic
3. Build Model
4. Presentations (watch video)

10 Earth Interior(3).ppt 20 MARKS
1. 10 marks On a separate piece of paper (use an entire 81/2 by 11 sheet):
A. Draw and label:
Oceanic Crust, Continental Crust, Asthenosphere, Mojo, Upper Mantle, Lower
Mantle, Outer Core, Inner Core
B. Label (for each of the above in A.):
Thickness of each ‘layer’ 2278e.g. Inner Core = 2, 278 km
C. Label (for each of the above in A.):
Consistency & composition of each ‘layer’ e.g. Inner Core = Solid Iron
2. 2 marks Name the two types of body waves. Explain the two key differences
between these waves.
3. 2 marks Explain how we know where the mantle/core divide is and how we
know what the core = solid & mantle = liquid. Essentially, talk about how each
wave travels and how waves can be reflected/refracted.
4. 2 marks Who discovered the Moho, and how did he do so?
5. 1 mark I bet you $1 000 000 I can run around the earth faster than you. One of
us runs on the Equator, one of us on the Prime Meridian. Which one do you want
and why?
6. 1 mark Explain how my laying down in bed and then getting up is like
isostacy/isostatic rebound (hint: focus on what’s happening to the mattress).
7. 2 mark Is magnetic declination and magnetic inclination the same thing or
different? Explain your answer.
9 Seismology.ppt 11 MARKS
1. 1 mark Write in correct chronological order: earthquake, aftershock,
foreshock.
2. 1 mark Draw a very simple diagram (or series of diagrams) illustrating fault
creep.
3. 1 mark What is the difference between the epicenter and the focus of an
earthquake?
4. 1 mark What is the difference between the Moho and the Benioff Zone?
5. 2 marks What are the two types of Body Waves. Describe two differences
between them.
6. 1 mark
7. 1 mark Name the two types of surface waves and in a quick sketch for each
