l Imelanbrphosed it changes into different rocks depending on the extent of metamorphism. Show the steps that occur with higher grades of metamor- phism. What minerals form in this process? 8. Along a certain steep-sided stream valley slate dips into the hillside on one side of the stream and into the valley on the other. Draw this in cross section. A road is to be placed along the base of the valley wall by removing rock in a side hill cut. On which side of the stream should the cut be placed? Explain. Why is this so? In addition to the foliation, what other rock weak nesses would be of concern? How would this affect the road cut? 9. A schist sample has an unconfined compressive le iot failure) of 17.000 psi. If the

Solution

the road should be constructed on the valley side. because its need more resources and money to construct into slate dips side. cracks, fractures and presence of should be investigated. it may lead collapse of the rock mass.
