Question

As this lab is worth two labs, two to four questions will be utilized for your prelab quiz. | What is the difference between "poorly sorted" and "well-sorted" material (as it relates to deposition processes)? Briefly explain your reasoning. Give an example of a transportation force that would likely be responsible for poorly-sorted and well-sorted sedimentary deposits. Briefly explain your rationale and reasoning. How does climate affect the potential for landslides? Briefly explain your reasoning but be specific. How does topography affect the potential for landslides? Briefly explain your reasoning but be specific in landscape position susceptibility. What is the difference between "glacial outwash" and "glacial till"? What type of "sorting (well/poor) would you expect with each and why? Briefly explain your reasoning. Briefly describe a typical sequence of layering on a hillside/bluff in the Puget Sound Region. Minimally include 4 different layers (these are specific layers with names) and an explanation of what each layer is composed of and visual characteristics, if applicable.

Explanation / Answer

1. What is the difference between poorly sorted and well sorted material in deposition processes?

very poorly sorted describe the amount of variance seen in particle sizes

well sorted indicates that the sediment sizes are similar (low variance).

2.Give an example of transportation force that would likely be responsible for poorly sorted and well sorted deposits.

Answer: Gravity force:Sediment transport is only due to gravity can occur on sloping surfaces in general, including hillslopes, scarps, cliffs, and the continental shelf

3. How does climate affect the potential for landslides?

Climate change can alter landslides by processes via increasing air temperatures, higher intensity and frequent heavy rain events, decreasing summer precipitation etc.Increasing air temperatures can facilitate soil breakdown, allow more water to penetrate soils which can affect the likelihood of landslides.A higher likelihood of landslides, primarily as a result of higher soil water content

landslides are the most common type of landslide and is caused by heavy rainfall. The climate changes affect the stability of natural and engineered slopes and have consequences on landslides.

4. How does topography affect the potential for landslides?

The susceptibility of a given area to landslides can be determined and depicted using hazard zonation. As the slope information you can get from topography.Steep slope more suscepitibility to landslide.In the steep, rugged terrain heavy precipitation often triggers numerous shallow landslides. Since soil-moisture conditions, intense or sustained rainfall, and steep convergent topography provide the necessary conditions for slope failure.
