I already posted requirements below…………………………………………………..
1.Choose a type of physical weathering and explain how it works and what makes it a physical
weathering process.
2.Choose a type of chemical weathering and explain how it works and what makes it a chemical
weathering process.
3.Explain the differences between the follow forms of sediment transport:
a.
Dissolved load
b.
Suspended load
c.
Bed load
4.What is the Reynolds’ number and what is it used to describe?
5.How do cross-laminae differ from planar-laminae?
6.How does trough cross-laminae differ from planar cross-laminae?
7.What controls the formation of trough cross-laminae vs. planar cross-laminae?
8.How do soft-sediment deformation features such as load, ball & pillow or flame structures from?
9.How does a flute cast differ from a tool mark?
10.What is the difference between supratidal, intertidal, and subtidal?
1
11.How do mud drapes form? In what environment would you likely find this feature?
12.Hummocky cross-stratification is usually created by what process?
13.What is wave base? How does fair-weather wave base differ from storm-weather wave base?
14.What distinguishes flaser bedding from wavy bedding from lenticular bedding?
15.What is the main control determining if a coastline will be tidal dominated vs. storm/wave
dominated?
16.What depositional environment would you expect on a coastline that is dominated by tidal
ranges greater than 4 m. Describe not only the environment, but detail on sediments and structures
that would be expected as well.
17.What type of sediment and sedimentary structure would be expected in the following
environment?
a. Bay/Lagoon
b. Dune
c. Foreshore
d. Upper Shoreface
e. Middle Shoreface
f. Lower Shoreface

20.What is the cause of tides?
21.What are the two components that determine if a barrier island will form?
22.Abyssal plain sedimentation – what are the sources and controls?
23.What is a Turbidite?
a. Where are they mainly deposited?
b. Sketch a Bouma Sequence stratigraphic column of an idealized turbidite deposit.
24.Sketch a planar (map) view of a turbidite deposits in the shelf/slope/plain environments – label the
type of sediments you would find at each location.
3
25.Explain or show the flow direction(s) indicated by the cross-stratification.
a. What is the name of this cross-stratification?
b. What depositional environment is this cross-stratification of?
4
26.Use the diagram below to answer the following:
a. What is the following diagram called?

28.Label the depositional environment above.
29.For each of the label, what sediment and structures would you anticipate depositing?
30.Does the above image show a barrier system that is prograding or retrograding?
31.For your answer in 30, what are the conditions that can cause this to occur?
