Investigating Mass Wasting In this activity you will explore the interaction of the three factors that lead to mass wasting landslides: « the type of material « the slope of the material « the saturation of water in the material Select a material and a saturation level, then adjust the slope until you find the minimum slope angle that causes mass wasting. Record this in the table in the next tab. Reset and repeat until you have completed the table, then answer the analysis questions that follow.

Investigating Mass Wasting Analysis Questions As you conduct your experiments, record the results in the observation table. Your goal is to find the minimum slope angle that causes a mass wasting event under each of the nine conditions. When you have completed the table, answer the analysis questions that follow.

Next — e — 1. a) What is the relationship between the minimum slope angle and saturation for each of the three materials? Student's Answer: Suggested Answer ~ The minimum slope angle needed to cause a mass wasting event declines as the saturation level increases from low to high. The more water there is in the sediments, the easier they will slide off the hill. Compare Answer Hide Answer 1. b) Explain why this relationship occurs. As the saturation of each material increases, the slope angle decreases. For clay, it is most prominent, as it has a very low « Student's Answer: Suggested Answer ~ The more water in the sediment, the less able it is to bind together by the force of friction. This makes it easier for it to flow downbhill at a lower slope angle. | think it's because more saturations means the wetter the material becomes, which can cause more slippage. v +« Previous Next —
2. Rank the three materials (clay, gravel, and layered) according to their ability to withstand mass wasting. The first should be the material most able to withstand mass wasting and the third should be the material least able to withstand mass wasting.

No real correlation exists The larger the particle size, the less water it takes to overcome the force of friction holding them together The smaller the particle size, the less water it takes to overcome the force of friction holding them together The smaller the particle size, the more water it takes to overcome the force of friction holding them together +/ Correct! + Previous
