Question

I need help with question number 5 for this assaigment 

 

C. Figure A10.2.2 is an oblique view of a small outcrop of fine-grained layered rock that
contains fossils. The layers probably represent bedding planes. The layers are inclined and
the sense of inclination can be determined by noticing the water in the lower-left corner of
the photograph.
1. Using the water line as a guide, carefully draw a strike line near the top of one of
the flat layers using the black-and-white image for your drawing. (Make sure your
teacher can see the strike line you draw.) Remember that a strike line is a
horizontal line on the inclined surface and that the water is a horizontal surface.
2. Examine the photograph carefully and imagine a ball rolling down the inclined
surface. Now draw what you infer to be a dip vector extending from the strike line
using the black-and-white image for your drawing.
3. Identify which end of the strike line points toward the Right-Hand-Rule reference
strike. Label that end of the strike line with "RHR." Refer to Fig. 10.2 for help
visualizing the RHR reference strike.
4. Let's assume that the geoscientist was pointing the camera due north when this
photograph was taken. In what general direction do these beds dip?
5. You cannot directly measure the dip angle in this view, but you can estimate the
dip angle within perhaps 10° or so. About what is the dip angle of these beds?
