1.Select a type of physical weathering and explain how it works and what distinguishes it from other types of weathering.
2.Select a type of chemical weathering and describe how it works and what distinguishes it from other types of weathering.
3.Explain how the following types of sediment transfer differ:
a. Load that has been dissolved
b. Load in suspension
c. The weight of the bed
4.What is the Reynolds number, and what does it mean?
5.How are cross-laminae and planar-laminae different?
6.What is the difference between trough cross-laminae and planar cross-laminae?
7.What factors influence the establishment of trough vs. planar cross-laminae?
8.What are the origins of soft-sediment deformation features like load, ball & pillow, and flame structures?
9.What is the difference between a fluted cast and a tool mark?
10.How do you distinguish between supratidal, intertidal, and subtidal?
11.What causes mud drapes to form? In what kind of environment are you most likely to come across this feature?
12.What is the most common cause of hummocky cross-stratification?
13.What is the definition of wave base? What is the difference between a fair-weather wave base and a storm-weather wave base?
14.How is laser bedding different from wavy bedding and lenticular bedding?
15.What is the key factor that determines whether a coastline is tidal or storm/wave-dominated?
16.On a coastline dominated by tidal ranges greater than 4 m, what depositional environment would you expect? Not only the environment, but also the sediments and structures that would be expected, should be described in depth.
17.In the following environment, what kind of sediment and sedimentary structure might be expected?
d. Face of the Upper Shore
e. Face of the Middle Shore
Lower Shoreface (f)
18. In the figure below, arrange the depositional habitats from step 17.
19.What are the three most important factors that influence the deposition of a siliciclastic coastline?
20.What causes tidal waves?
21.What are the two factors that influence the formation of a barrier island?
22.What are the origins and controls of abyssal plain sedimentation?
23.What is the definition of turbidite?
a. Where do they usually end up?
b. Draw a stratigraphic column of an idealized turbidite deposit in the Bouma Sequence.
24.Draw a planar (map) view of turbidite deposits in shelf, slope, and plain habitats, labeling the many types of sediments you’d find there.
25.Explain or demonstrate the cross-flow stratification’s direction(s).
a. What does this cross-stratification go by?
b. What is the depositional context in which this cross-stratification occurs?
26.Answer the following questions using the diagram:
a. What is the name of the diagram below?
b. What is it supposed to describe?
c. What causes Clay/Silt to act the way it does in the diagram?
27.Draw a sand ripple’s general bed form and name the following:
a. Direction of Flow
c. Sides of Stoss and Lee
top set, foreset, and bottom set are all examples of topset.
d. Points of Attachment and Separation
g. Where does erosion/deposition happen?
28.Assign a name to the above-mentioned depositional environment.
29.What sediment and structures do you expect to be deposited for each label?
30.Does the above image depict a prograding or retrograding barrier system?
31.In your answer to question 30, what are the conditions that could lead to this?
