Question
Chapter 11, Problem 3FQ
To determine
Whether a strike to the southwest differ from a strike to the northeast.
Expert Solution & Answer
Answer to Problem 3FQ
No, both southwest strike and northeast strike are the same.
Explanation of Solution
The bearings or the positions of inclined rock layers on the Earth are defined by means of their strike and dip by the Earth scientists. Strike refers to the compass direction that marks the meeting between a sloping rock and a horizontal plane. In other words, strike describes the direction where the rock layers geographically extend.
Strike direction is expressed by its azimuth. From the accompanying figure, the strike direction of the tilted rock layers is identified as SW-NE. Here, the strike direction can be mentioned as SW or NE, since both indicate the same direction of geographical extent. According to the directions, SW and NE lie opposite to each other of a compass, and hence fall on the same plane. Therefore, there is no difference between a SW strike and a NE strike.

The top echelon of the city government changed a few years ago, but they did not replace many staff. Nonetheless, the situation is such that the city is led by a corrupt mayor who has realized dded that elections are approaching. Opinion polls suggest that a significant part of the electorate has the environment as a major concern. Close associates of the mayor organized a focus group and chose to investigate several initiatives which they felt might be possible to conduct in a relatively short amount of time.
