(Section: 3 / Paragraph: a / Sub-Paragraph: XV / Line: 1)
Question "For a stream gradient (and a slope), should the students measure the distance along the stream, or along a straight line between the beginning and end points? The same question for a slope, if measured for a trail/road that is not straight."
For questions regarding slope : sec 3- paragraph a-subparagraph XIV- line 1 and gradient : sec 3- paragraph a-subparagraph XV- line 1 In both cases, unless a specific question states otherwise, measurements should be made along the path of the stream or road rather than in a straight line.
