- In creating your Concept Sketch you will need to ensure the following:
- Essential ideas all shown
- Important relationships correctly portrayed
- No conceptual errors or evidence of misunderstanding.
- Your Concept Sketch should be detailed, and clearly drawn
- To not lose points, make sure that your Concept Sketch is properly labeled.
- Your assignment should be completed one side of an 8½ ” x 11” sheet of paper.
- You will turn in your Concept Sketch assignment by uploading a digital image of your sketch, either as a scanned copy, or a digital photograph (using a digital camera, smartphone, or tablet, etc.). To upload a digital copy of your sketches, use the link provided within Canvas. It is recommended that the digital copies be a jpeg or pdf file.
- Please inspect your digital file before submitting it to make sure it is legible. If your submission is not legible, you will receive a grade of one point (1) for that assignment.
- Please check that your concept sketch uploads are in the proper orientation, i.e., it should not be upside down or sideways. Several scanning apps are available for free online for your smartphone, tablet, or PC.
Questions. Choose 1 option from the list below.
1. Sketch and explain each of the five principles of relative dating, providing an example of each principle (4.1).
2. Sketch and label a series of diagrams depicting development of the three main types of unconformities (angular unconformity, nonconformity, and disconformity), and describe what sequence of events is implied by each type (4.2A, B, C). For this question, label the location of the unconformity, the youngest rock units, and the oldest rock units.
3. Sketch, label, and describe the major layers of Earth (5.1A). Include in your description the composition and thickness of each layer. Use a separate sketch to help you describe the difference between continental crust and oceanic crust (5.1A [inset]). Next, sketch and describe the difference between lithosphere and asthenosphere (5.1B). Finally, use sentences (no sketch) to describe why some regions have high elevations (5.1C).
4. Sketch and label an oceanic divergent boundary (mid-ocean ridge), and describe what happens as plates spread apart (5.10A). In addition, sketch a column depicting and describing the four types of igneous rocks that form along oceanic divergent margins (5.10B).
5. Sketch and describe the four main types of volcanoes that construct hills and mountains. Include the types of eruptions that form each type and a separate sketch of the relative sizes of different types of volcanoes (6.3).
6. Sketch, label, and explain the four stages in the formation of a caldera. Include labels on the features associated with your diagram (i.e., magma, eruption column, etc.) (6.9B).
7. Sketch, label, and describe the main types of faults (7.2C). In addition, sketch, label, and describe how horsts and grabens form and explain their geologic significance to the American Southwest (7.2D).
8. Sketch and explain the two types of body waves and two types of surface waves. (7.6A)
