1. List the environments in which shale forms. What is the one thing that each has in common with the others?

 

 

 

 

2. What evidence would indicate that sandstones form on the Earth's surface and not beneath the surface?

 

 

 

 

3.What is the general relationship between particle size and distance of transport for sediments from a source? (think about the distance and size of sediments transported by rivers to the continental shelf).

 

 

 

4. Many limestones are dense, fine grained and black or dark in color.  How would you distinguish them from basalt which is an igneous rock?

 

 

 

5. Many beaches on the volcanic islands of the pacific are white.  The islands, however are composed of black basalt, which has no quartz and gives rise to black sand beaches. What do you suppose is the composition of the white beach sands?
