Sediments

In the southwestern part of the map, along the Shenandoah River, the sediments are only Quaternary in age, yet they are surrounded by much older Cambrian sediments.  How do you explain this?  In the southeastern corner of the map, locate Rockville and Gaithersburg.  Notice that they are separated by the Plummer’s Island Fault.  Is Rockville […]

A tree trunk is buried in sediments. Minerals slowly take the place of the materials that formed the tree trunk. Even the structures of the cells are preserved. What do we call a fossil that forms in this way?

What are the different types of seafloor sediments, and what are the factors that control the distribution of each major sea sediment type? Where does each major seafloor sediment type tend to accumulate in greatest quantity (i.e., discuss the distribution of these sediments)?

sedimentary rocks formed by compaction and cementation of land – derived sediments are classified on the basis of   

What are sediments? How are sediments formed? What are sources of sediments? Make a list and give a brief description in your own words. Examine the diagram above. Where do terrigenous sediments accumulate? Why do they accumulate here? What happens to the size of sediment as you get farther away from the shoreline? Explain what […]
