S.I. Session 12 Quiz

This quiz covers material from the lecture on Monday, September 26^th.

Part a) Match the term to its definition:

                TERMS:

a)Shale                                                 b)Basin                 c) Compressive

d)Tensional Tectonics                    e)Dome                               f)Joint

g)Tensional                                         h)Anticline          i)Syncline

                DEFINITIONS:

1)__This rock does not permit the transmission of fluids, it has low porosity and is referred to as a good trapping rock.

                                2)__These geologic structures fold upwards.

3)__Geologic structure created by subsidence due to overlying sediment.

4)__These forces bend rocks into curved shapes.

5) __These geologic structures fold downwards.

6)__This geologic structure is created when sediments are eroded over an igneous intrusion.

7)__This is a rock fracture without movement along the fracture plane.

8)__These forces cause normal faulting.

9)__Continental rifting occurs because of this process.

Part b) Draw a picture of continental rifting. Label the upper crust, lower crust, and brittle-ductile transition:

Part c) True or False:

                Mark T (true) or F (false) in the blank provided:

                                1)__Compression forces cause folding.

2)__Folds are exclusively small in scale.

3)__At a left bend in a right lateral transform fault, compressive forces are present.

4)__Older rocks lying above younger rocks is a sign of compressive tectonics.

5)__Oil and gas sink to the bottom of geologic formations.

6)__ The San Andreas fault is a left lateral strike slip fault.
