Geology 104 Study Questions:
Sedimentary Rocks

 

1.

What are the six processes by which sediments are created and then lithified to become sedimentary rocks?

 

2.

Explain the difference between chemical and physical weathering.

 

3.

What factors determine how fast a rock will break apart or weather (know at least 2 of 4)?

 

4.

Clastic sediments have been created by what kind of weathering?

 

5.

Where are rocks likely to weather more rapidly: Antarctica or the African Rain Forest? Why?

 

6.

How does the speed of water/wind relate to the amount and size of sediments that can be transported?

 

7.

Explain the difference between a boulder and a conglomerate? A sand and a sandstone? A clay and a shale?

 

8.

List at least three type of chemical sedimentary rocks. Explain which minerals they contain and how they might be formed.

 

9.

How does burial change the make-up of a sediment and make it easier to lithify?

 

10.

What is cementation?

 

11.

What are sedimentary structures?

 

12.

Explain the difference between a cross-bed and a graded bed. Why are graded beds so useful to geologists in the field? What do graded beds have in common with mud cracks?

 

13.

Which side of a ripple mark faces the prevailing wind or water direction?

 

14.

Give an example of a bioturbation structure.
